Cautions for use
For a capacitor of pin 1 and pin 25 against electric mirror, use a capacitor about twice in capacitance of the input
capacitor.
In the sample application circuit, a 0.47
F capacitor is used for the input capacitor of 0.22F.
Connect a capacitor of each pin of 1 and 25 to Pre GND similarly to the case of input capacitor.
