AAT3239

500mA MicroPower™ LDO

PowerLinear

General Description

Features

The AAT3239 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 AAT3239 has

been specifically designed for high-speed turn-on

and turn-off performance, fast transient response,

good power supply rejection ratio (PSRR), and is

reasonably low noise, making it ideal for powering

sensitive circuits with fast switching requirements.

•

500mA Output Current

Low Dropout: 400mV at 300mA

High Accuracy: ±2.0%

70µA Quiescent Current

Fast Line and Load Transient Response

High-Speed Device Turn-On and Shutdown

High Power Supply Rejection Ratio

Low Self Noise

Short-Circuit Protection

Over-Temperature Protection

Uses Low Equivalent Series Resistance

(ESR) Ceramic Capacitors

Noise Reduction Bypass Capacitor

Shutdown Mode for Longer Battery Life

Low Temperature Coefficient

TSOPJW 8-Pin Package

Other features include low quiescent current, typical-

ly 70µA, and low dropout voltage which is typically

less than 400mV at 300mA. The device is output

short-circuit protected and has a thermal shutdown

circuit for additional protection under extreme operat-

ing conditions.

•

The AAT3239 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 AAT3239's reference output to

ground.

Applications

•

Cellular Phones

Digital Cameras

Notebook Computers

Personal Portable Electronics

Portable Communication Devices

The AAT3239 is available in a Pb-free, 8-pin

TSOPJW package in factory-programmed voltages.
