LR1801
Preliminary
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.
 FEATURES
* Ultra Low Dropout Voltage
* Low Ground Pin Current
* The Guaranteed Output Current is 1A DC
* Output Voltage Accuracy ± 1.5%
* Over temperature Protection And Over current Protection
