... Output Capacitor ( The S-812C Series has an internal phase compensation circuit which stabilizes the operation regardless of the change of output load. Therefore it is possible for users to have a stable operation without an output capacitor (C ). However, the values of output overshoot and undershoot, which are the L characteristics of transient response, vary depending on the output capacitor. In selecting the value of output capacitor, refer to the data on C characteristics” ...
