AIC AIC1723A-27CETR 500ma low dropout linear regulator Datasheet

AIC1723A
500mA Low Dropout Linear Regulator
FEATURES
DESCRIPTION
Low Dropout Voltage of 650mV at 500mA
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.
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.

Specifications are production tested at TA =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).
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.
