DESCRIPTION

A6250A series is a group of positive voltage output, low power consumption, low dropout voltage, three terminal regulator. It can provide 250mA output current when input / output voltage differential drops to 430mV (VOUT=2.8V). The very low power consumption of A6250A (IQ=1.0uA) can greatly improve natural life of batteries.

A6250A can provide output value in the range of 1.1V~5.5V in 0.1V steps. It also can be customized on command.

A6250A includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.

A6250A has well load transient response and good

temperature characteristic , a nd it uses trimming

technique to guarantee output voltage accuracy

within 2.

The A6250A is available in SOT 23 SOT 25 and

SOT89 3 packages.
