HIGH PSRR, LOW DROPOUT,

400mA ADJUSTABLE LDO

REGULATOR



DESCRIPTION

The UTC LR1143 is a CMOS-based 400mA voltage regulator

with low supply current, low dropout, adjustable output voltage,

The device offering high PSRR and low dropout. The quiescent

current is as low as 35μA, further prolonging the battery life. The

UTC LR1143 also works with low-ESR ceramic capacitors,

reducing the amount of board space necessary for power

applications, critical in handheld wireless devices.

The UTC LR1143 consumes typical 0.7μA in shutdown mode.

The other features include low dropout voltage, high output

accuracy, current limit protection, and enable/shutdown control.



FEATURES

* Wide operating voltage range : 3.0V~5.5V

* Adjustable output voltage

* Enable/shutdown control

* Low-noise for RF application

* Ultra-Fast response in line/load transient

* Current limit protection

* Output only 1μF capacitor required for stability

* High power supply rejection ratio
