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 voltage. Typical ground current
remains approximately 65 µ A, for loading
ranging from zero to maximum. Dropout
voltage turns substantially low when output
current is 500mA. Built-in output current
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.
