Description

The AIC1722 is a 3-pin low dropout linear regulator. The superior characteristics of the product  include zero base current loss, very low dropout voltage, and 2% accuracy output voltage.Typical ground current remains approximately 55A, from no load to maximum loading conditions. Dropout voltage at 100mA output current is exceptionally low:130mV for the AIC1722-50 and AIC1722-52 , 180mV  for  the  AIC1722-33,AIC1722-35,and AIC1722-37 AIC1722-38.Output current limiting and thermal limiting are built in to provide maximal protection to the product against fault conditions.

The AIC1722 comes in the popular 3-pin SOT-89 and TO-92 packages.
