DESCRIPTION
The AIC1722A is a 3-pin low dropout linear
regulator. The superior characteristics of the
AIC1722A include zero base current loss,
very low dropout voltage, and 2% accuracy
output voltage. Typical ground current
remains approximately 55µA, from no load to
maximum loading conditions. Dropout voltage
at 300mA output current is exceptionally low.
Output current limiting and thermal limiting are
built in to provide maximal protection to the
AIC1722A against fault conditions.
The AIC1722A comes in the popular 3-pin
SOT-89, TO-92 and SOT-23 packages.
APPLICATIONS
Voltage Regulator for CD-ROM Drivers.
Voltage Regulator for LAN Cards.
Voltage Regulator for Microprocessor.
Wireless Communication Systems.
Battery Powered Systems.
