*1. VOUT(S): Specified output voltage
VOUT(E): Effective output voltage
i.e., the output voltage when fixing IOUT(=10 mA) and inputting VOUT(S)+2.0 V.
*2. Output current at which output voltage becomes 95% of VOUT(E) after gradually increasing output current.
*3. Vdrop = VIN1−(VOUT(E) × 0.98), where VIN1 is the Input voltage at which output voltage becomes 98% of VOUT(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
