Note: Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=300mA.

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

Typical Application Circuit

ACE555

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