(6) Typical numbers are at 25°C and represent the most likely norm.
(7) VOUT(E) : Effective Output Voltage ( Ie. The output voltage when VIN = (VOUT +1.0V)
and maintain a certain IOUT Value).
(8) VOUT : Specified Output Voltage.
(9) VDO : The Difference Of Output Voltage And Input Voltage When Input Voltage Is Decreased Gradually
Till Output Voltage Equals To 98% Of VOUT (E).
