Note 1: VOUT (E) =Effective Output Voltage (i.e. the output voltage when “VOUT (T) +1.0V” is provided at the VIN pin while maintaining a
certain IOUT value).
2: VOUT (T) =Specified Output Voltage
3: VIN (MIN) =VOUT+VDROPOUT
4: To prevent the Short Circuit Current protection feature from being prematurely activated, the input voltage must be applied before
a current source load is applied.
