300mA MicroPower™

High Performance LDO Linear Regulator

General Description

Features

PowerLinear™

The AAT3238 MicroPower low dropout (LDO) linear

regulator is ideally suited for portable applications

where very fast transient response, extended battery

life, and small size are critical. The AAT3238 has

been specifically designed for high-speed turn-on

and turn-off performance, fast transient response,

good power supply ripple rejection (PSRR), and is

reasonably low noise, making it ideal for powering

sensitive circuits with fast switching requirements.

Other features include low quiescent current, typical-

ly 70µA, and low dropout voltage, typically less than

400mV at the maximum output current level of

300mA. The device is output short-circuit protected

and has a thermal shutdown circuit for additional pro-

tection under extreme operating conditions.

The AAT3238 also features a low-power shutdown

mode for extended battery life. A reference bypass

pin has been provided to improve PSRR perform-

ance and output noise by connecting a small exter-

nal capacitor from the AAT3238's reference output to

ground.

The AAT3238 is available in a Pb-free, space-saving

6-pin SOT23 or 8-pin SC70JW package in factory-

programmed voltages.
