n DESCRIPTION
The AIC1739 is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1739 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
is exceptionally low. Output current limiting
and thermal limiting are built in to provide
maximal protection to the AIC1739 against
fault conditions.
The AIC1739 comes in the popular 3-pin
SOT-89 and TO-92 packages.
