AIC1723A

500mA Low Dropout Linear Regulator

ꢀFEATURES

ꢀ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.

ꢁ Low Dropout Voltage of 650mV at 500mA

Output Current (3V Output Version).

ꢁ Guaranteed 500mA Output Current.

ꢁ Maximum Input Voltage is 8V

ꢁ Low Ground Current at 65µA.

ꢁ 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.

ꢁ Only needs 4.7µF Output Capacitor for Stability.

ꢁ Current and Thermal Limiting.

ꢀAPPLICATIONS

ꢁ CD-ROM Drivers.

The AIC1723A is available with popular SOT-

23, SOT-223, SOT-89 and TO-252 packages.

ꢁ LAN Cards.

ꢁ Microprocessor.

Note 1:

Specifications are production tested at T_A=25°C. Specifications over the -40°C to 85°C operating

temperature range are assured by design, characterization and correlation with Statistical Quality

Controls (SQC).

Note 2:

Note 3:

Note 4:

Regulation is measured at constant junction temperature, using pulse testing with a low ON time.

Current limit is measured by pulsing a short time.

Dropout voltage is defined as the input to output differential at which the output voltage drops

100mV below the value measured with a 1V differential.
