● About Input-to-output capacitor
It is recommended that a capacitor is placed nearby pin between Input pin and GND, output pin and GND.
A capacitor, between input pin and GND, is valid when the power supply impedance is high or drawing is long. Also as for a
capacitor, between output pin and GND, the greater the capacity, more sustainable the line regulation and it makes improvement
of characteristics by load change. However, please check by mounted on a board for the actual application. Ceramic capacitor
usually has difference, thermal characteristics and series bias characteristics, and moreover capacity decreases gradually by
using conditions.
For more detail, please be sure to inquire the manufacturer, and select the best ceramic capacitor.
