Note 1: VOUT (E) =Effective Output Voltage (i.e. the output voltage when “VOUT (T) + 2.0V” 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.
