 DESCRIPTION

The AIC1723 is a 3-pin low dropout linear

regulator. The superior characteristics of the

AIC1723 include zero base current loss, very

low dropout voltage, and 2% accuracy output

voltage. Typical ground current remains

approximately

65µA, from no load to maximum loading

conditions. Dropout voltage at 500mA output

current is exceptionally low: 750mV for the

AIC1723-50 and AIC1723-52, 900mV for the

AIC1723-38, AIC1723-37, AIC1723-35, and the

AIC1723-33. Output current limiting and thermal

limiting are built in to provide maximal protection

to the AIC1723 against fault conditions.

The AIC1723 comes in the popular SOT-223,

TO-251 and TO-252 packages.
