Note: Vdrop=Vin 1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=300mA.

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

Typical Application Circuit

ACE515

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

Explanation：

ACE515 series is a group of positive voltage output, low noise, low power consumption, low dropout

voltage regulator.

ACE515 can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be

customized on command.

ACE515 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver

module.

ACE515 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%.
