VOUT (T) ：Specified Output Voltage 2.VOUT (E) ：Effective Output Voltage ( ie. The output voltage when “VOUT (T)+1.0V”is provided at the Vin pin while maintaining a certain Iout value.) 3.VDIF：VIN1 –VOUT (E)’ VIN1 ：The input voltage when VOUT(E)’ appears as input voltage is gradually decreased. VOUT (E)’=A voltage equal to 9 8% of the output voltage whenever an amply stabilized Iout and {VOUT (T)+1.0V} is input.
