REGULATOR



DESCRIPTION

The UTC LR1112 is a CMOS-based 150mA voltage regulator

with low supply current, low dropout, adjustable and fixed output

voltage, The device consists of pass element, error amplifier,

band-gap, current limit and thermal shutdown circuitry. The

device is turned on when EN pin is set to logic high level.


