1A FAST ULTRA LOW

DROPOUT LINEAR

REGULATOR

DESCRIPTION

The UTC LR1108 operate from a +2.5V ~ +7.0V input supply as

fast ultra low-dropout linear regulators. Wide output voltage range

options are available. The fast response characteristic to make UTC

LR1108

suitable for low voltage microprocessor application. The low

quiescent current operation and low dropout quality caused by the

CMOS process.

The

UTC

LR1108

has

ultra

low

dropout

voltage;

300mV at 1A load current typically.

The ground pin current is typically 200uA at 1mA load current.

ERROR Flag: When the output voltage drops 10% below nominal

value Error flag goes low.

Output Voltage Precision: Multiple output voltage options are

available and ranging from 1.2V ~ 5.0V at room temperature with a

guaranteed accuracy of ±1.5%, and ±3.0% when varying line, load

and temperature.

FEATURES

* Ultra Low Dropout Voltage

* Low Ground Pin Current

* 0.04% Load Regulation

* The Guaranteed Output Current is 1A DC

* Output Voltage Accuracy ± 1.5%

* ERROR Flag Indicates Output Status

* Low Output Capacitor Required

* Over temperature Protection And Over current Protection
