LR1107 LR1107E Datasheet

600mA FAST ULTRA LOW DROPOUT LINEAR REGULATOR


 
DESCRIPTION
 
The UTC LR1107/E 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
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 200uA 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.
