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

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 AIC1739 against

fault conditions.

The AIC1739 comes in the popular 3-pin

SOT-89 and TO-92 packages.
