AAT3239 - 500mA MicroPower LDO

Datasheet Summary

Description

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.

Features

  • include low quiescent current, typically 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 operating conditions. The AAT3239 also features a low-power shutdown mode for extended battery life. A reference bypass pin has been provided to improve PSRR performance and output noise by connecting a small external capacitor from the AAT3239's reference output.

www.DataSheet4U.com AAT3239 500mA MicroPower™ LDO General Description 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. Other features include low quiescent current, typically 70µA, and low dropout voltage which is typically less than 400mV at 300mA.
