Low Dropout Voltage of 900mV at 500mA  
Output Current (3.0V Output Version).  
The AIC1740 is a 3-pin low dropout linear  
regulator. The superior characteristics of the  
AIC1740 include zero base current loss, very  
low dropout voltage, and 2% accuracy output  
voltage. Typical ground current remains
