DESCRIPTION
The AIC1723A is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1723A include zero base current loss,
very low dropout voltage, and 2% accuracy
output
remains approximately 65 µ A, for loading
ranging from zero to maximum. Dropout
voltage turns substantially low when output
current is 500mA.
limiting and thermal limiting provide maximal
protection to the AIC1723A against fault
conditions.
The AIC1723A is available with popular SOT-
23, SOT-223, SOT-89 and TO-252 packages.
