DESCRIPTION

A6201A series is a group of positive voltage output, low power consumption, low dropout voltage, three terminal regulator. It can provide 200mA output current when input / output voltage differential drops to 418mV (VOUT= 3.3V), And it also provides foldback short-circuit protection and output current limit function. The very low power consumption of A6201A (IQ=3uA) can greatly improve natural life of batteries.

A6201A can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customized on command.

A6201A includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.

A6201A has well load transient response and good temperature characteristic, And it uses trimming technique to guarantee output voltage accuracy within±2.

The A6201A is available in SOT-23 and SOT89-3 Packages
