UNISONIC TECHNOLOGIES CO., LTD

LR1107/E

600mA FAST ULTRA LOW

DROPOUT LINEAR REGULATOR

CMOS IC

Â DESCRIPTION

The UTC LR1107/E 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

LR1107/E suitable for low voltage microprocessor application. The low

quiescent current operation and low dropout quality caused by the

CMOS process.

The UTC LR1107/E has ultra low dropout voltage; 300mV at

600mA load current typically.

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

SET/ADJ Mode (for LR1107): Connect an external resistive

voltage-divider from VOUT to this pin to set the output voltage from

1.145V to 5V.

ERROR Flag (for LR1107E): 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 Â±1.5%, and Â±3.0% when varying line, load and temperature.

Â FEATURES

* Ultra Low Dropout Voltage

* Low Ground Pin Current

* 0.68% Load Regulation

* The Guaranteed Output Current is 600mA DC

* Output Voltage Accuracy Â± 1.5%

* ERROR Flag Indicates Output Status

* VOUT can be Adjusted From 1.145V to 5V.

* Low Output Capacitor Required

* Overtemperature Protection and Overcurrent Protection
