About input/output capacitor
It is recommended to place a capacitor as close as possible to the
pins between the input terminal and GND or between the output
terminal and GND.
The capacitor between the input terminal and GND becomes valid
when source impedance increases or when wiring is long. The
larger the capacity of the output capacitor between the output
terminal and GND is, the better the stability and characteristics in
output load fluctuation become. However, please check the status
of actual implementation. Ceramic capacitors generally have
variation, temperature characteristics, and direct current bias
characteristics and the capacity value also decreases with time
depending on the usage conditions. It is recommended to select a
ceramic capacitor upon inquiring about detailed data of the related
manufacturer.
●
About the equivalent series resistance (ESR) of a ceramic capacitor
Capacitors generally have ESR (equivalent series resistance) and it
operates stably in the ESR-IOUT area shown on the right. Since
ceramic capacitors, tantalum capacitors, electrolytic capacitors, etc.
generally have different ESR, please check the ESR of the
capacitor to be used and use it within the stability area range shown
in the right graph for evaluation of the actual application.
