*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)+2.0 V.
*2. Output current at which output voltage becomes 95% of V_OUT(E) after gradually increasing output current.
*3. V_drop = 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.
[ ] [ ] [ ] ^∆VOUT mV/°C ^*1 = VOUT(S) V ^*2 × ^∆VOUT ppm/°C ^*3 ÷ 1000
