4. Discharge shunt function
The S-11L10 Series has a built-in discharge shunt circuit to discharge the output capacitance. When the ON / OFF
pin is set to OFF level, turns the output transistor off, and turns the discharge shunt function on so that the output
capacitor discharges. The VOUT pin is set to the V_SS level faster, compared to the product which does not have a
discharge shunt circuit.
