Low Dropout Linear Regulator
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.
