ACE500E
Fast Transient Response LDO with Adjustable Output Voltage
Description
ACE500E is a 500mA low noise and fast transient response liner regulator with adjustable output voltage
and ultra low dropout voltage. Its output voltage is programmed by a resistor divider, and can be as low as
0.8V, which satisfies the most advanced ICs which may require supply voltage to be 0.9V – 1.2V.
ACE500E is consists of a precise voltage reference, an error amplifier, a compensation network and a
low ON-resistance power P-MOSFET. It also integrates many protection circuitry, like current limit and
over-temperature protection module.
