AIC1722A

300mA Low Dropout Linear Regulator

FEATURES

Low Dropout Voltage of 470mV at 300mA Out-

put Current (3.0V Output Version).

Guaranteed 300mA Output Current.

Maximum Input Voltage is 8V

Low Ground Current at 55碌A.

2% Accuracy Output Voltage of 1.8V/ 2.0V

/2.5V /2.7V/ 3.0V/ 3.3V/ 3.5V/ 3.7V/ 3.8V/ 5.0V/

5.2V.

Needs only 1碌F for Stability.

Current and Thermal Limiting.

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 55碌A, 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.
