 AIC1723A 500mA Low Dropout Linear Regulator FEATURES DESCRIPTION The AIC1723A is a 3-pin low dropout linear Low Dropout Voltage of 650mV at 500mA regulator. The superior characteristics of the Output Current (3V Output Version). AIC1723A include zero base current loss, Guaranteed 500mA Output Current. very low dropout voltage, and 2% accuracy Maximum Input Voltage is 8V output voltage. Typical ground current Low Ground Current at 65µA. remains approximately 65 µ A, for loading 2% Accuracy Output Voltage of 1.8V/ 2.0V ranging from zero to maximum. Dropout /2.5V /2.7V/ 3.0V/ 3.3V/ 3.5V/ 3.7V/ 3.8V/ 5.0V/ voltage turns substantially low when output 5.2V. current is 500mA. Built-in output current Only needs 4.7µF Output Capacitor for
