These regulators feature low dropout voltages and ultralow quiescent current compared to conventional LDO regulators. Offered in a 5-terminal small outline integrated-circuit SOT-23 package, the TPS769xx series devices are ideal for micropower operations and where board space is at a premium. VI = 4.3 V CO = 4.7 F 20 19 IO = 100 mA 18 IO = 0 mA 17 A combination of new circuit design and process 16 innovation has enabled the usual PNP pass transistor to be replaced by a PMOS pass 15 element. Because the PMOS pass element -60 -40 -20 0 20 40 60 80 100 120 140 behaves as a low-value resistor, the dropout TA - Free-Air Temperature - C voltage is very low, typically 71 mV at 100 mA of load current (TPS76950), and is directly proportional to the load current. Since the PMOS pass element is a voltage-driven device, the quiescent current is ultralow (28 A maximum) and is stable over the entire range of output load current (0 mA to 100 mA). Intended for use in portable systems such as laptops and cellular phones, the ultralow-dropout voltage feature and ultralow-power operation result in a significant increase in system battery operating life. The TPS769xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 A typical at TJ = 25C. The TPS769xx is offered in 1.2-V, 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.2 V to 5.5 V).

JUNE 1999 - REVISED MAY 2001 APPLICATION INFORMATION The TPS769xx family of low-dropout (LDO) regulators have been optimized for use in battery-operated equipment. They feature extremely low dropout voltages, low quiescent current (17 A nominally), and enable inputs to reduce supply currents to 1 A when the regulators are turned off. device operation The TPS769xx uses a PMOS pass element to dramatically reduce both dropout voltage and supply current over more conventional PNP-pass-element LDO designs. The PMOS pass element is a voltage-controlled device and, unlike a PNP transistor, it does not require increased drive current as output current increases. Supply current in the TPS769xx is essentially constant from no load to maximum load. Current limiting and thermal protection prevent damage by excessive output current and/or power dissipation. The device switches into a constant-current mode at approximately 350 mA; further load reduces the output voltage instead of increasing the output current. The thermal protection shuts the regulator off if the junction temperature rises above approximately 165C. Recovery is automatic when the junction temperature drops approximately 25C below the high temperature trip point. The PMOS pass element includes a back gate diode that conducts reverse current when the input voltage level drops below the output voltage level. A voltage of 1.7 V or greater on the EN input will disable the TPS769xx internal circuitry, reducing the supply current to 1A. A voltage of less than 0.9 V on the EN input will enable the TPS769xx and will enable normal operation to resume. The EN input does not include any deliberate hysteresis, and it exhibits an actual switching threshold of approximately 1.5 V. A typical application circuit is shown in Figure 21.

A higher-value electrolytic input capacitor may be necessary if large, fast-rise-time load transients are anticipated and the device is located several inches from the power source. Like all low dropout regulators, the TPS769xx requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance is 4.7 F. The ESR (equivalent series resistance) of the capacitor should be between 0.2 and 10 . to ensure stability. Capacitor values larger than 4.7 F are acceptable, and allow the use of smaller ESR values. Capacitances less than 4.7 F are not recommended because they require careful selection of ESR to ensure stability. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described above. Most of the commercially available 4.7 F surface-mount solid tantalum capacitors, including devices from Sprague, Kemet, and Nichico, meet the ESR requirements stated above. Multilayer ceramic capacitors may have very small equivalent series resistances and may thus require the addition of a low value series resistor to ensure stability. CAPACITOR SELECTION PART NO.

This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than or equal to PD(max). The maximum-power-dissipation limit is determined using the following equation: P T max * T J A + D(max) R qJA Where: TJmax is the maximum allowable junction temperature RJA is the thermal resistance junction-to-ambient for the package, see the dissipation rating table. TA is the ambient temperature. The regulator dissipation is calculated using: P D + VI * VO I O Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the thermal protection circuit. regulator protection The TPS769xx PMOS-pass transistor has a built-in back diode that conducts reverse current when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting might be appropriate. The TPS769xx features internal current limiting and thermal protection. During normal operation, the TPS769xx limits output current to approximately 350 mA. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds approximately 165C, thermal-protection circuitry shuts it down. Once the device has cooled down to below approximately 140C, regulator operation resumes. 14 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 PACKAGE OPTION ADDENDUM www.ti.com 23-Oct-2010 PACKAGING
