150mA, LOW QUIESCENT CURRENT, FAST TRANSIENT
LOW DROPOUT LINEAR 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.
