NOTE:

1. VOUT: Specified Output Voltage.

2. VOUT (E) : Effective Output Voltage ( I.e. The Output Voltage When VIN = (VOUT +1.0V)

And Maintain A Certain IOUT Value).

3. Vdiff: The Difference Of Output Voltage And Input Voltage When Input Voltage Is

Decreased Gradually Till Output Voltage Equals To 98% Of VOUT (E); When VOUT<2.0V,

VIN≥2.0V Should be Guaranteed.
