UNISONIC TECHNOLOGIES CO., LTD
LR3965
CMOS IC
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
deliver 1.5A. Wide range of preset output voltage options are
available. Built-in low on-resistance transistor provides low dropout
voltage and large output current. The UTC LR3965 is designed and
optimized for battery-powered systems to work with low noise.
The UTC LR3965 consumes less than 0.01μA in shutdown
mode. Other features include ultra low dropout voltage, current
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
