3.0A LOW DROPOUT LINEAR

REGULATOR

DESCRIPTION

The LR3966 is a low-noise, low-dropout linear regulator

operated from a 2.5V to 6V input voltage and is guaranteed to

deliver 3A output current. Wide range of preset output voltage

options are available. Built-in low on-resistance transistor provides

designed and optimized for battery-powered systems to work with

low noise.

The LR3966 is developed on a CMOS process technology

which allows low quiescent current operation independent of output

load current.. This CMOS process also allows the LR3966 to operate

under extremely low dropout conditions.

FEATURES

* 3A Guaranteed Output Current

* Ultra Low Dropout Voltage

* Low Ground Pin Current

* Low Temperature Coefficient

* Current Limiting Protection

* Thermal Shutdown Protection

* Excellent Line/Load Transient
