Caution Generally a series regulator may cause oscillation, depending on the selection of external parts.

Confirm that no oscillation occurs in the application for which the above capacitors are used.



The S-19200 Series requires an output capacitor between the VOUT pin and the VSS pin for phase compensation.

Operation is stabilized by a ceramic capacitor with an output capacitance of 0.1

μF or more over the entire temperature

range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must

be 0.1

μF or more.

The values of output overshoot and undershoot, which are transient response characteristics, vary depending on the

value of the output capacitor.

The required value of capacitance for the input capacitor differs depending on the application.
