

DESCRIPTION

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

process.

SOT-23-5

SOT-23

(JEDEC TO-236)

(EIAJ SC-59)

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 V_OUTto this pin to set the output voltage from

1.145V to 5V.

SOT-25

SOT-89

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.
