Technical Terms
Generally in voltage regulator, output capacitor is used to stabilize regulation and to improve the
characteristics of transient response. The S-812C Series operates stably without output capacitor C
Thus the output capacitor C
that users will use the S-812C Series, and they are not cautious about the transient response, it is
possible to omit an output capacitor. If using an output capacitor for this IC, users are able to use devices
such as ceramic capacitor which has small ESR (Equivalent Series Resistance).
The accuracy of the output voltage ± 2.0% is assured under the specified conditions for input voltage,
which differs depending upon the product items, output current, and temperature.
Indicate the dependency of the output voltage against the input voltage. That is, the value shows how
much the output voltage changes due to a change in the input voltage after fixing output current constant.
