7 Detailed Description

7.1 Overview

The LM2990 is a three-terminal, low dropout, 1-A negative voltage regulator available with fixed output voltages

of −5, −5.2, −12, and −15 V. The LM2990 is a negative power supply ideally suited for a dual-supply system

when using together with LM2940 series. The device may also be used as a fixed or adjustable current sink load.

7.2 Functional Block Diagram

7.3 Feature Description

7.3.1 Fixed Output-Voltage Options

The LM2990 provides 4 fixed output options: −5 V, −5.2 V, −12 V, and −15 V. Output voltage accuracy is

ensured to ±5% over load and temperature extremes.

7.3.2 Low Dropout Voltage

Generally speaking, the dropout voltage (VDO) refers to the voltage difference between the IN pin and the OUT

pin when the PNP pass element is fully on and is characterized by the classic Collector-to-Emitter saturation

voltage, VCE(SAT). VDO indirectly specifies a minimum input voltage above the nominal programmed output voltage

at which the output voltage is expected to remain within its accuracy boundary.

7.3.3 Short Circuit Protection (Current Limit)

The internal current limit circuit is used to protect the LDO against high-load current faults or shorting events. The

LDO is not designed to operate in a steady-state current limit. During a current-limit event, the LDO sources

constant current. Therefore, the output voltage falls when load impedance decreases. Note also that if a current

limit occurs and the resulting output voltage is low, excessive power may be dissipated across the LDO, resulting

in a thermal shutdown of the output. A fold back feature limits the short-circuit current to protect the regulator

from damage under all load conditions. If OUT is forced below 0 V before EN goes high, and the load current

required exceeds the fold back current limit, the device may not start up correctly.

SNVS093G –JUNE 1999–REVISED MAY 2015

Feature Description (continued)

7.3.4 Thermal Protection

The device contains a thermal shutdown protection circuit to turn off the output current when excessive heat is

dissipated in the LDO. The thermal time-constant of the semiconductor die is fairly short, and thus the output

cycles on and off at a high rate when thermal shutdown is reached until the power dissipation is reduced. The

internal protection circuitry of the device is designed to protect against thermal overload conditions. The circuitry

is not intended to replace proper heat sinking. Continuously running the device into thermal shutdown degrades

its reliability.

7.4 Device Functional Modes

7.4.1 Operation with VOUT(TARGET) –5 V ≥VIN > –26 V

The device operates if the input voltage is within VOUT(TARGET) –5 V to –26 V range. At input voltages beyond the

VIN requirement, the devices do not operate correctly, and output voltage may not reach target value.

8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The LM2990 is a 1-A negative voltage regulator with an operating VIN range of –6 V to –26 V, and a regulated

VOUT having 5% accuracy with a maximum rated IOUT current of 1 A. Efficiency is defined by the ratio of output

voltage to input voltage because the LM2990 is a linear voltage regulator. To achieve high efficiency, the dropout

voltage (VIN – VOUT) must be as small as possible, thus requiring a very low dropout LDO.

Successfully implementing an LDO in an application depends on the application requirements. If the

requirements are simply input voltage and output voltage, compliance specifications (such as internal power

dissipation or stability) must be verified to ensure a solid design. If timing, start-up, noise, PSRR, or any other

transient specification is required, the design becomes more challenging.

8.2 Typical Application

8.2.1 –5 V Post Regulator for an Isolated Switching Power Supply

Figure 20. Post Regulator for an Isolated Switching Power Supply

8.2.1.1 Design Requirements

For this design example, use the parameters listed in Table 1 as the input parameters.

Table 1. Design Parameters

DESIGN PARAMETER DESIGN REQUIREMENT

Input voltage –10 V, provided by the DC-DC converter switching at 1 MHz

Output voltage -5 V, ±10%

Output current 5 mA to 400 mA

RMS noise, 10 Hz to 100 kHz < 1 mVRMS, IOUT = 5 mA

PSRR at 1KHz > 45 dB, IOUT = 5 mA

8.2.1.2 Detailed Design Procedure

At 400-mA loading, the dropout of the LM2990 has 1-V maximum dropout over temperature, thus an –5 V

headroom is sufficient for operation over both input and output voltage accuracy. The efficiency of the LM2990 in

this configuration is VOUT / VIN = 50%.

To achieve the smallest form factor, the TO-263(KTT) package is selected. Input and output capacitors should be

selected in accordance with the External Capacitors section. Aluminum capacitances of 470 μF for the input and

50-μF capacitors for the output are selected. With an efficiency of 50% and a 400-mA maximum load, the internal

power dissipation is 2000 mW, which corresponds to 82.5°C junction temperature rise for the TO-263 package.

With an 25°C ambient temperature, the junction temperature is at 107.5°C.

www.ti.com

SNVS093G –JUNE 1999–REVISED MAY 2015

8.2.1.2.1 External Capacitors

The LM2990 regulator requires an output capacitor to maintain stability. The capacitor must be at least 10-μF

aluminum electrolytic or 1-μF solid tantalum. The equivalent series resistance (ESR) of the output capacitor must

be less than 10 Ω, or the zero added to the regulator frequency response by the ESR could reduce the phase

margin, creating oscillations. An input capacitor, of at least 1-μF solid tantalum or 10-μF aluminum electrolytic, is

also needed if the regulator is situated more than 6 from the input power supply filter.

8.2.1.2.2 Forcing The Output Positive

Due to an internal clamp circuit, the LM2990 can withstand positive voltages on its output. If the voltage source

pulling the output positive is DC, the current must be limited to 1.5 A. A current over 1.5 A fed back into the

LM2990 could damage the device. The LM2990 output can also withstand fast positive voltage transients up to

26V, without any current limiting of the source. However, if the transients have a duration of over 1 ms, the

output should be clamped with a Schottky diode to ground.

8.2.1.3 Application Curves

Figure 22. LM2990-5 Line Transient Response Figure 23. LM2990-5 Load Transient Response

8.2.2 Fixed or Adjustable Current Sink

The LM2990 is configurable as a fixed or adjustable current sink. As Figure 24 and Figure 25 show, the sink

current is determined by the resistor value — to achieve adjustable sink current, add one adjustable resistor

between output and load.

9 Power Supply Recommendations

The LM2990 is designed to operate from an input voltage supply range between –6 V and –26 V. The input

voltage range should provides adequate headroom in order for the device to have a regulated output. This input

supply must be well regulated.

10 Layout

10.1 Layout Guidelines

For best overall performance, place all circuit components on the same side of the circuit board and as near as

practical to the respective LDO pin connections. Place ground return connections to the input and output

capacitor, and to the LDO ground pin as close to each other as possible, connected by a wide, component-side,

copper surface. The use of vias and long traces to create LDO circuit connections is strongly discouraged and

negatively affects system performance. This grounding and layout scheme minimizes inductive parasitics, and

thereby reduces load-current transients, minimizes noise, and increases circuit stability. A ground reference

plane is also recommended and is either embedded in the PCB itself or located on the bottom side of the PCB

opposite the components. This reference plane serves to assure accuracy of the output voltage, shield noise,

and behaves similar to a thermal plane to spread (or sink) heat from the LDO device. In most applications, this

ground plane is necessary to meet thermal requirements.

Input-Output Differential: The voltage difference between the unregulated input voltage and the regulated

output voltage for which the regulator will operate.

Line Regulation: The change in output voltage for a change in the input voltage. The measurement is made

under conditions of low dissipation or by using pulse techniques such that the average chip

temperature is not significantly affected.

Load Regulation: The change in output voltage for a change in load current at constant chip temperature.

Long Term Stability: Output voltage stability under accelerated life-test conditions after 1000 hours with

maximum rated voltage and junction temperature.

Output Noise Voltage: The rms AC voltage at the output, with constant load and no input ripple, measured over

a specified frequency range.

Quiescent Current: That part of the positive input current that does not contribute to the positive load current.

The regulator ground lead current.

Ripple Rejection: The ratio of the peak-to-peak input ripple voltage to the peak-to-peak output ripple voltage.

Temperature Stability of VOUT:The percentage change in output voltage for a thermal variation from room

temperature to either temperature extreme.

11.2 Trademarks

All trademarks are the property of their respective owners.

(1) The marketing status values are defined as follows:

ACTIVE: Product device recommended for new designs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.

OBSOLETE: TI has discontinued the production of the device.

(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance

do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may

reference these types of products as "Pb-Free".

RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.

Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based

flame retardants must also meet the <=1000ppm threshold requirement.

(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation

of the previous line and the two combined represent the entire Device Marking for that device.

(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two

lines if the finish value exceeds the maximum column width.
