DESCRIPTION

A6141 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. It can provide 150mA output current when input / output voltage differential drops to 400mV (VOUT= 5V), and it also provides foldback short-circuit protection, thermal protection and output current limit function. The very low power consumption of A6141 (Iq=2.5uA) can greatly improve natural life of batteries.

A6141 can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customize on command.

A6141 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.

A6141 has well load transient response and good temperature characteristic. A6141 uses trimming technique to guarantee output voltage accuracy within±2.

The A6141 is available in SOT89-3 package.
