1.0A FAST ULTRA LOW DROPOUT LINEAR REGULATOR

DESCRIPTION

The UTC LR1805/LR1805AD 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 LR1805/LR1805AD suitable for low

voltage microprocessor application. The low quiescent current

operation and low dropout quality caused by the CMOS process.

The UTC LR1805/LR1805AD has low dropout voltage. The

ground pin current is typically 60uA.

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 LR1805-xx are fixed one in

the IC and UTC LR1805AD are adjustable one.

FEATURES
