1A FAST ULTRA LOW

DROPOUT LINEAR

REGULATOR



DESCRIPTION

SOT-223

CMOS IC

TO-252

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.

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

OUT

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,

load and temperature.
