LR1108 LR1108E LR1108N Datasheet



The UTC LR1108/E/N is an ultra low-dropout linear

regulators. Wide output voltage range options are available. The

fast response characteristic to make UTC LR1108/E/N suitable

for low voltage microprocessor application. The low quiescent

current operation and low dropout quality caused by the CMOS


The UTC LR1108/E/N has ultra low dropout voltage

300mV at 1A load current typically.

The ground pin current is typically 150uA at 1mA load current.

ERROR Flag: When the output voltage drops 10% below

nominal value Error flag goes low.

SET/ADJ Mode (for LR1108): Connect an external resistive

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

1.145V to 5V.

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




* Ultra Low Dropout Voltage

* Low Ground Pin Current

* 0.65% Load Regulation

* The Guaranteed Output Current is 1A DC

* Output Voltage Accuracy ± 1.5%

* ERROR Flag Indicates Output Status

* Sense option improves better load regulation

* Low Output Capacitor Required

* Over temperature Protection And Over current Protection
