UTC LR1107
UNISONIC TECHNOLOGIES CO., LTD
LR1107/E
600mA FAST ULTRA LOW
DROPOUT LINEAR REGULATOR
CMOS IC
DESCRIPTION
The UTC LR1107/E is an ultra low-dropout linear regulators.
Wide output voltage range options are available. The fast response
characteristic to make UTC LR1107/E suitable for low voltage
microprocessor application. The low quiescent current operation and
low dropout quality caused by the CMOS process.
The UTC LR1107/E has ultra low dropout voltage; 300mV at
600mA load current typically.
The ground pin current is typically 150uA at 1mA load current.
SET/ADJ Mode (for LR1107): Connect an external resistive
voltage-divider from VOUT to this pin to set the output voltage from
1.145V to 5V.
ERROR Flag (for LR1107E): 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
* Ultra Low Dropout Voltage
* Low Ground Pin Current
* 0.55% Load Regulation
* The Guaranteed Output Current is 600mA DC
* Output Voltage Accuracy ± 1.5%
* ERROR Flag Indicates Output Status
* VOUT can be Adjusted From 1.145V to 5V.
* Low Output Capacitor Required
* Overtemperature Protection and Overcurrent Protection
