LR1102  
CMOS IC  
LOW NOISE 150mA LDO  
REGULATOR  
DESCRIPTION  
The UTC LR1102 families are CMOS-based voltage  
regulator ICs with extremely low supply current, high output  
voltage accuracy, high Ripple Rejection and chip enable circuit.  
These ICs performance are excellent and with SOT-25  
package, thus these ICs are very suitable for hand-held  
communication equipment.  
FEATURES  
* Ultra-Low Supply Current : Typ. 35µA  
* Standby Mode: Typ. 0.1µA  
* Low Dropout Voltage: Typ. 0.2V (IOUT = 100mA)  
* Excellent Line Regulation: Typ. 0.05%/V  
* High Ripple Rejection: Typ. 70dB (f = 1kHz)
