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.
Please attach an anti-oscillation capacitor between V
GND.

right. Generally, ESR of ceramic, tantalum and electronic
capacitor etc. is different for each, so please be sure to check
a capacitor which is going to use, and use it inside the stable
operating region, showed right. Then, please evaluate for the
actual application.
