Block Diagram

Explanation

ACE520 series are highly accurate, dual, low noise, CMOS low dropout voltage regulators. The output

voltage for each regulator is set independently by trimming. Voltages are selectable in 100mV steps within

a range of 1.2V to 3.5V. It also can be customized on command.

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

module.

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%.
