Description

The ACE5012C is a group of positive voltage output, low power consumption, low dropout voltage

regulator. The very low power consumption of ACE5012C (0.8uA, Typ) can greatly improve natural life of

batteries. The ACE5012C includes high accuracy voltage reference, error amplifier and output driver

module with discharge capability. And it also provides foldback short-circuit protection, thermal protection

and output current limit function.

The ACE5012C can provide output value of fixed version as 1.2V, 1.8V, 2.5V, 2.8V, 3V, and 3.3V. It also

can be customized on command.
