Caution

The above connection diagram and constant will not guarantee successful operation. Perform

thorough evaluation using the actual application to set the constant.



Condition of Application

Input capacitor (CIN):

0.1

μF or more

Output capacitor (CL):

0.1

μF or more

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.



Selection of Input and Output Capacitors (CIN, CL)

The S-1313 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 value of the output overshoot or undershoot transient response varies depending on the value of the output

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

The recommended capacitance for an application is CIN

≥ 0.1 μF, CL ≥ 0.1 μF; however, when selecting the output

capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.
