Electrical Characteristics for All Products
Generally, the characteristics of power supply ICs change according to temperature fluctuations. 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.

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.
