Notes:

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)+2.0V.

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.
