Preliminary Datasheet

LP3981H

500mA Output,Low noise,Low-Dropout

CMOS Linear Regulator

General Description

Features

The LP3981H series low-dropout, low-power

regulators offer a fast start-up and excellent line and

load transient responses. A low ground current while

at no load with chips enabled makes the devices

attractive for battery-operate power systems. The

LP3981H series also provides an active pull-down

circuit to quickly discharge output load. Other features

include short current limit, thermal protection and a low

current consume shut-down mode.

 2.5V~5.5V Input Voltage Range

 Low Dropout: 260mV @ 300mA

 500mA Output Current

 High PSRR: -63dB at 1KHz

 <0.1uA Standby Current In Shutdown Mode

 TTL-Logic-Controlled Shutdown Input

 Ultra-Fast Response in Line/Load transient

 Current Limit and Thermal Shutdown Protection

Applications

The LP3981H is available in SOT23-5 packages.
