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

µA, 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 AIC1737

against fault conditions.

The AIC1737 comes in the popular 3-pin SOT-89

packages.
