1.5A LOW DROPOUT LINEAR

REGULATOR

DESCRIPTION

The UTC LR3965 belonged to low-noise, low-dropout, linear

regulators operate from 2.25V to 6V input and are guaranteed to

available. Built-in low on-resistance transistor provides low dropout

optimized for battery-powered systems to work with low noise.

The UTC LR3965 consumes less than 0.01μA in shutdown

limiting protection, thermal shutdown protection and high ripple

rejection ratio.

FEATURES

* 1.5A Guaranteed Output Current

* 0.01μA Shutdown Current

* 40mV Dropout at 150mA Load

* Low Temperature Coefficient

* Current Limiting Protection

* Thermal Shutdown Protection

* Excellent Line/Load Transient

* Sense Option Improves Load Regulation
