AIC1722A
300mA Low Dropout Linear Regulator
ꢀFEATURES
ꢀDESCRIPTION
ꢁ Low Dropout Voltage of 470mV at 300mA Out-
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.
put Current (3.0V Output Version).
ꢁ Guaranteed 300mA Output Current.
ꢁ Maximum Input Voltage is 8V
ꢁ Low Ground Current at 55µA.
ꢁ 2% Accuracy Output Voltage of 1.8V/ 2.0V

Note 1:
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).
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.
