General Description
The HT75XX-1 series is a set of three-terminal high cur-
rent low voltage regulator implemented in CMOS tech-
nology. They can deliver 100mA output current and
allow an input voltage as high as 24V. They are avail-
able with several fixed output voltages ranging from
2.1V to 12.0V. CMOS technology ensures low voltage
drop and low quiescent current.
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain variable voltages and currents.
