●Vo Terminal

Be sure to place an anti-oscillation capacitor between the output terminal and the GND. Oscillations may arise if the

capacitance value changes, due to factors such as temperature changes. A 1

μF capacitor with small internal series resistance

(ESR) such as a ceramic capacitor is recommended as an anti-oscillation capacitor. Ceramic capacitors generally have

favorable temperature characteristics and DC bypass characteristics. When selecting a ceramic capacitor, a high voltage

capacitor (good DC bypass characteristics) with temperature characteristics that are superior to those of X5R or X7R, is

recommended. In applications where input voltage and load fluctuations are rapid, please decide on a capacitor after

sufficiently confirming its properties according to its specifications in the actual application.
