*1. V_OUT(E): Effective output voltage
i.e., The output voltage when fixing I_OUT(=30 mA) and inputting V_OUT(S)+1.0 V.
V_OUT(S): Specified output voltage
*2. Output amperage when output voltage goes below 95 % of V_OUT(E) after gradually increasing output current.
*3. The output current can be at least this value.
Use load amperage not exceeding this value.
