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.
