The specification Tj = 25℃ is based on a state where temperature increase has no effect (assuming no fluctuation in the characteristics) as ascertained by pulse tests. Standard Application Circuit Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND. The capacitances should be determined experimentally. In particular, adequate investigation should be made so that there is no problem even in high or low temperature. 1 2VIN TA48xxF/S VOUT COUTCIN 0.33 µF 33 µF
