Note: Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=500mA.

Vin1 is the input voltage at which the output voltage becomes 98% of Vout1 after gradually decreasing the input voltage.

Typical Application Circuit

Note: Input capacitor (Cin=1uF) and Output capacitor (Cout=1uF) are recommended in all application circuit.

Explanation：

ACE519C series is a group of positive voltage output, low noise, low power consumption, low dropout

voltage regulator.

ACE519C can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized

on command.

ACE519C includes high accuracy voltage reference, error amplifier, current limit circuit and output driver

module.

ACE519C 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%.
