DESCRIPTION
The AIC1727 is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1727 include zero base current loss, low
dropout voltage and accurate output voltage.
Typical ground current remains approximately 4
A, from no load to maximum loading
conditions.
The AIC1727 comes in the popular 3-pin SOT-
23, SOT-89, TO-92 packages.

Note 1:
Guaranteed by design.
Note 2:
Regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Note 3:
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.
