Description

ACE501 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

400mV (Vin=4.0V. Vout=3.0V).The very low power consumption of ACE501 (lq=3.0uA) can greatly

improve natural life of batteries.

ACE501 can provide output value in the range of 1.2V~6.0V in 0.1V steps. It also can customized on

command.

ACE501 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver

module.

ACE501 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%.

ACE501 is available in SOT-89-3. SOT-23-3 package which is lead free. It also can available in these

packages with lead.
