*1) VOUT(S)=Specified output voltage
VOUT(E)=Effective output voltage, i.e., the output voltage at fixet IOUT(=30 mA) and input VOUT(S)+1.0 V.
*2) Output current when the output voltage goes below 95% of VOUT(E) after gradually increasing output current.
*3) Vdrop = VIN1-(VOUT(E) × 0.98)
VIN1 = Input voltage when output voltage falls 98% of VOUT(E) after gradually decreasing input voltage.
*4) Output voltage shift by temperature [mV/°C] is calculated using the following equation.
∆VOUT
∆Ta • VOUT
