AIC1734

300mA Low Dropout Linear Regulator

ꢀFEATURES

ꢀDESCRIPTION

ꢁ Low Dropout Voltage of 470mV at 300mA Out-

The AIC1734 is a 3-pin low dropout linear

regulator. The superior characteristics of the

AIC1734 include zero base current loss, very

low dropout voltage, and 2% accuracy output

voltage. Typical ground current remains ap-

proximately 55µA, for loading ranging from

zero to maximum. Dropout voltage at 300mA

output current is exceptionally low. Built-in

output current limiting and thermal limiting

provide maximal protection to the AIC1734

against fault conditions.

Note 4:

Guaranteed by design.

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.

Note5:

Specifications are guaranteed by Statistical Quality Controls (SQC), with no production test proved,

when operating temperature ranges from -40°C to 85°C.
