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.
FEATURES
* 150mA low dropout regulator with EN
* Very low IQ over full load: 30µA
* Wide input voltage range: 2.5~6V
* Wide adjustable output: 0.8V~5.0V
* Fixed output options: 1.0V~3.3V
* Fast start-up time: 80µs
* PSRR: 65dB at 100Hz
* Stable with low ESR, 1µF ceramic output capacitor
* Low dropout: 150mV typical at 150mA
* Excellent Load/Line Transient Response
* Current limit protection
* Ambient temperature range: -40ºC~85°C
