DESCRIPTION
The AIC1737 is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1737 include zero base current loss, very low
dropout voltage, and 2% accuracy output voltage.
Typical ground current remains approximately 55
Dropout voltage is exceptionally low. Output
current limiting and thermal limiting are built in to
provide maximal protection to the AIC1737
against fault conditions.
The AIC1737 comes in the popular 3-pin SOT-89
packages.
A, from no load to maximum loading conditions.
