Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=300mA or Iout=500mA.
Vin1 is the input voltage at which the output voltage becomes 98% of Vout1 after gradually decreasing the input voltage.

Explanation：
ACE509 series is a group of positive voltage output, low noise, low power consumption, low dropout
voltage regulator.
ACE509 can provide output value in the range of 1.2V~4.5V every 0.1V step. It also can be customized
on command.
ACE509 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE509 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%.
