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.
