1A FAST ULTRA LOW

DROPOUT LINEAR

REGULATOR



DESCRIPTION

The UTC LR1801 operate from a +2V ~ +6V input supply as

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

options are available. The fast response characteristic to make

UTC LR1801 suitable for low voltage microprocessor application.

The low quiescent current operation and low dropout quality

caused by the CMOS process.

The

UTC

LR1801

has

ultra

low

dropout

voltage

300mV at 1A load current typically. The ground pin current is

typically 60uA at 1mA load current.

Output Voltage Precision: Multiple output voltage options are

available and ranging from 1.2V ~ 3.5V at room temperature with a

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

and temperature.


