DESCRIPTION
The AIC1735 is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1735 include zero base current loss, very
low dropout voltage, and 2% accuracy output
voltage.

at 100mA output current is exceptionally low.
Output current limiting and thermal limiting are
built in to provide maximal protection to the
AIC1735 against fault conditions.
The AIC1735 comes with the popular SOT-
223 and TO-252 packages.

Note 4:
Guaranteed by design.
Regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Current limit is measured by pulsing a short time.
Dropout voltage is defined as the input to output differential at which the output voltage drops
100mV below the value measured with a 1V differential.
