*1. VOUT(S)=Specified output voltage

VOUT(E)=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.

*3. Vdrop=VIN1*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.

[ ] [ ] [ ] ∆VOUT mV/°C *1 = VOUT(S) V *2 × ∆VOUT ppm/°C *3 ÷ 1000

∆Ta

∆Ta • VOUT

*1. Temperature change ratio for output voltage

*2. Specified output voltage

*3. Output voltage temperature coefficient

*5. These figures mean that every part can supply output current at least to these values
