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

55

µA, 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.
