LP38691/LP38693

500mA Low Dropout CMOS Linear Regulators

Stable with Ceramic Output Capacitors

General Description

The LP38691/3 low dropout CMOS linear regulators provide

tight output tolerance (2.0% typical), extremely low dropout

voltage (250 mV @ 500mA load current, V

OUT = 5V), and

excellent AC performance utilizing ultra low ESR ceramic

output capacitors.

The low thermal resistance of the LLP, SOT-223 and T0-252

packages allow the full operating current to be used even in

high ambient temperature environments.

The use of a PMOS power transistor means that no DC base

drive current is required to bias it allowing ground pin current

to remain below 100 µA regardless of load current, input

voltage, or operating temperature.

Dropout Voltage: 250 mV (typ) @ 500mA (typ. 5V out).

Ground Pin Current: 55 µA (typ) at full load.

Precision Output Voltage: 2.0% (25˚C) accuracy.
