Note 1: VOUT (T) =Specified Output Voltage.

2: 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).

3: Vdif=VIN

(Note4)-VOUT (E)

4: VIN1=The input voltage at the time 98% of VOUT (E) is output (input voltage has been gradually reduced).
