Notes:
1. V_OUT(S)=Specified output voltage
V_OUT(E)=Effective output voltage, i.e., the output voltage when fixing I_OUT(=10 mA) and inputting V_OUT(S)+2.0V.
2. Output current at which output voltage becomes 95% of V_OUT(E) after gradually increasing output current.
3. Vdrop=V_IN1-(V_OUT(E)×0.98), where V_IN1 is the Input voltage at which output voltage becomes 98% of V_OUT(E) after
gradually decreasing input voltage.
4. Temperature change ratio for the output voltage [mV/°C] is calculated using the following equation.
