DESCRIPTION
The AIC1722 is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1722 include zero base current loss, very
low dropout voltage, and 2% accuracy output
voltage. Typical ground current remains
approximately 55µA, 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 AIC1722 against fault
conditions.
The AIC1722 comes in the popular 3-pin
SOT-89 and TO-92 packages.
