LR1108 LR1108E Datasheet

1A FAST ULTRA LOW DROPOUT LINEAR REGULATOR 


 
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
 
* Ultra Low Dropout Voltage
* Low Ground Pin Current
* 0.04% Load Regulation  
* The Guaranteed Output Current is 1A DC
* Output Voltage Accuracy ± 1.5%
* ERROR Flag Indicates Output Status  
* Low Output Capacitor Required
* Overtemperature Protection And Overcurrent Protection
