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

thorough evaluation using an actual application to set the constants.



Condition of Application

Input capacitor (CIN):

A ceramic capacitor with capacitance of 1.0

μF or more is recommended.

Output capacitor (CL):

A ceramic capacitor with capacitance of 1.0

μF to 100 μF is recommended.

Caution Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external

parts. Perform thorough evaluation including the temperature characteristics with an actual

application using the above capacitors to confirm no oscillation occurs.



Selection of Input Capacitor (CIN) and Output Capacitor (CL)

The S-19212B/DxxA Series requires CL between the VOUT pin and the VSS pin for phase compensation. The

operation is stabilized by a ceramic capacitor with capacitance of 1.0

μF to 100 μF. When using an OS capacitor, a

tantalum capacitor or an aluminum electrolytic capacitor, the capacitance also must be 1.0

μF to 100 μF. However, an

oscillation may occur depending on the equivalent series resistance (ESR).

Moreover, the S-19212B/DxxA Series requires CIN between the VIN pin and the VSS pin for a stable operation.

Generally, an oscillaiton may occur when a voltage regulator is used under the conditon that the impedance of the

power supply is high.

Note that the output voltage transient characteristics varies depending on the capacitance of CIN and CL and the value

of ESR.

Caution Perform thorough evaluation including the temperature characteristics with an actual application to

select CIN and CL.
