=Effective output voltage
i.e., The output voltage when fixing IOUT (
=30 mA) and inputting VOUT(S)+1.0 V.
*2.
Output current at which output voltage becomes 95 % of VOUT(E) after gradually increasing output current.

*1−(VOUT(E)×0.98)
*1.
The Input voltage at which output voltage becomes 98 % of VOUT(E) after gradually decreasing input
voltage.
*4.
Output voltage shift by temperature [mV/°C] is calculated using the following equation.
