(NOTE 1) VOUT(T) = Specified Output Voltage
(NOTE 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.)
(NOTE 3) Vdif = {VIN 1 (NOTE5) + VOUT 1 (NOTE4)}
(NOTE 4) VOUT1 = A voltage equal to 98% of the Output Voltage whenever an amply stabilized IOUT {VOUT(T)
+ 1.0V} is Input.
(NOTE 5) VIN 1 = The Input Voltage when VOUT 1 appears as Input Voltage is gradually decreased.
(NOTE 6) Unless otherwise stated, VIN = VOUT(T)+1.0V
