n DESCRIPTION
The AIC1732 is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1732 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 AIC1732-50 and AIC1732-52,
180mV for the AIC1732-33, AIC1732-34,
AIC1732-35, AIC1732-36, AIC1732-37 and
AIC1732-38. Output current limiting and
thermal limiting are built in to provide maximal
protection to the AIC1732 against fault
conditions.
The AIC1732 comes in the popular 3-pin
SOT-89 packages.
