*1. CIN is a capacitor for stabilizing the input.
*2. CL is a capacitor for stabilizing the output. A ceramic capacitor of 2.2 μF or more can be used.
*3. CDLY is the delay time adjustment capacitor.
*4. Rext is the external pull-up resistor for the reset output pin.
Connection of the external pull-up resistor is not absolutely essential since the S-19311 Series
has a built-in pull-up resistor.
Caution The above connection diagram and constants will not guarantee successful operation. Perform
thorough evaluation using an actual application to set the constants.
