Description

ACE502 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

470mV（Vout=2.0V）

。

The very low power consumption of ACE502（Iq=7uA）can greatly improve natural

life of batteries.

ACE502 can provide output value in the range of 1.5V~6.0V in 0.1V steps. It also can customized on

command.

ACE502 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver

module.

ACE502 has well load transient response and good temperature characteristic, which can assure the

stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy

within ±2%.

ACE502 is available in SOT-89-3、SOT-23-3、SOT-23-5 packages which is lead free，it also can available

in these packages with lead.
