INPUT
Output capacitors are generally used to stabilize regulation operation and to improve transient response
characteristics. But the S-812C series can provide stable operation without output capacitors. Capacitors
are used only to improve transient response characteristics. Output capacitors can hence be removed in
applications in which transient response can be negligible. When an output capacitor is used, a low ESR
(Equivalent Series Resistance) capacitor like ceramic capacitor can also be used.
The accuracy of the output voltage is
which differs depending upon the product items, output current, and temperature.
These parameters indicate the input voltage dependence on the output voltage. That is, the values show
how much the output voltage changes due to a change in the input voltage with the output current remained
unchanged.

If the above conditions change, the output voltage value may vary and go out of the accuracy range
of the output voltage. See the electrical characteristics and characteristics data for details.
