Note ：

1. VOUT (T) ：Output Voltage less than 1.8V, the input Voltage should be 2.8V at least, and the others fulfil the rule of Vin=Vout+1.

2.VOUT (E) ：Effective Output Voltage ( le. 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 98% of the output voltage whenever an amply stabilized IOUT {VOUT (T)+1.0V} is input.
