●Input-to-Output Capacitor
It is recommended that a capacitor (over 1uF) is placed near pins between the input pin and GND as well as the output pin
and GND. A capacitor, between input pin and GND, is valid when the power supply impedance is high or trace is long. Also,
as for the capacitor between the output pin and GND, the greater the capacitance, the more sustainable the line regulation
will be and the capacitor will make improvements of characteristics depending on the load. However, please check the
actual functionality of this part by mounting it on a board for the actual application. Ceramic capacitors usually have different,
thermal and equivalent series resistance characteristics, and moreover capacitance decreases gradually in use.
For additional details, please check with the manufacturer, and select the best ceramic capacitor for your application.
●Equivalent Series Resistance ESR (Output Capacitor)
To prevent oscillations, please attach a capacitor between
V
O
and GND. Capacitors usually have ESR (Equivalent
Series Resistance). Operation will be stable in the ESR-I
O
range shown to the right. Ceramic, tantalum and
electrolytic Capacitors have different ESR values, so
please ensure that you are using a capacitor that operates
in the stable operating region shown on the right. Finally,
please evaluate in the actual application.
