DESCRIPTION  
The UTC LR1101 series are ultra-low quiescent current CMOS  
LDO (Low Dropout Voltage). Designed for battery-powered system,  
the low 4μA quiescent current makes it an ideal choice. The Range  
of the output voltage is from 1.2V ~ 5V with 0.1V per step. And the  
max output current is 100mA.  
Wide range of available output fits most of applications. Built-in  
output current-limiting provide maximal protection against any fault  
conditions.  
*Pb-free plating product number:LR1101L  
„
FEATURES  
* 450mV typically dropout at 100mA  
* Ultra-low quiescent current: 4μA  
* Wide operating voltage ranges: 2V ~ 6V  
* Thermal current limiting protection  
* For stability only 1μF output capacitor is required  
* High power supply rejection ratio

APPLICATION INFORMATION  
Between VOUT and GND a 1μF (or larger) capacitor is recommended for stability. Without the capacitor the part  
may oscillate. When operating below -25℃ any type of capacitor can be used, but not Aluminum electrolytes. If  
there’s no limit the capacitance may be increased.  
Between VIN to GND a 1μF capacitor (or larger) should be placed.
