4. Discharge shunt function (S-1313 Series A / B types)
The S-1313 Series A / B types have built-in discharge shunt circuits to discharge the output capacitance. The output
capacitance is discharged as follows so that the VOUT pin reaches the VSS level.
(1) The ON / OFF pin is set to power-off level.
(2) The output transistor is turned off.
(3) The discharge shunt circuit is turned on.
(4) The output capacitor discharges
Since the S-1313 Series C / D types do no have discharge shunt circuits, the VOUT pin is set to VSS level through
several hundred k
Ω internal divided resistors between the VOUT and VSS pins. The S-1313 Series A / B types allow
for the VOUT pin reach the VSS level rapidly due to the discharge shunt circuits.

5. Constant current source pull-down (S-1313 Series A / C types)
In the S-1313 Series A / C types, the ON / OFF pin is internally pulled down to VSS, so the VOUT pin is in the VSS level
when in the floating status.
IC’s current consumption increases as much as 0.1
μA typ. of the constant current source when the ON / OFF pin is
connected to VIN and the S-1313 Series A / C types is operating.
