UNISONIC TECHNOLOGIES CO., LTD
LR1108
1A FAST ULTRA LOW
DROPOUT LINEAR
REGULATOR
CMOS IC
„ DESCRIPTION
The UTC LR1108 operate from a +2.5V ~ +7.0V input supply as
fast ultra low-dropout linear regulators. Wide output voltage range
options are available. The fast response characteristic to make UTC
LR1108 suitable for low voltage microprocessor application. The low
quiescent current operation and low dropout quality caused by the
CMOS process.
The UTC LR1108 has ultra low dropout voltage;
300mV at 1A load current typically.
The ground pin current is typically 200uA at 1mA load current.
ERROR Flag: When the output voltage drops 10% below nominal
value Error flag goes low.
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.
„ FEATURES
