Description

ACE520 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current.

The output voltage for each regulator is set independently by trimming. Output voltages are selectable in

The ACE520 includes two independent logic-controlled shutdown inputs and allows the output of each

regulator to be turned of independently.

The ACE520 includes high accuracy voltage reference, error amplifier, current limit circuit and output

driver module.

The ACE520 has excellent load and line transient response and good temperature characteristics, which

can assure the stability of chip and power system. And it uses trimming technique to guarantee output

voltage accuracy within± 2%.
