1A FAST ULTRA LOW

DROPOUT LINEAR

REGULATOR



DESCRIPTION

The UTC LR1811 operate from a +1.5V~+6V input supply as fast

ultra low-dropout linear regulators. Wide output voltage range

options are available. The fast response characteristic to make UTC

LR1811

suitable for low voltage microprocessor application. The low

quiescent current operation and low dropout quality caused by the

CMOS process.

The UTC LR1811 has low dropout voltage. The ground pin

current is typically 80μA.

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 and

load.

The output voltage types of UTC LR1811 are fixed one in the IC.



FEATURES

* Low Dropout Voltage

* The Guaranteed Output Current is 1A DC

* Output Voltage Accuracy ± 1.5%

* Over temperature Protection And Over current Protection
