4. Discharge shunt function (S-19244xxxH Series A / B / E / F type)
The S-19244xxxH Series A / B / E / F type has a built-in discharge shunt circuit 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 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-19244xxxH Series C / D / G / H type does not have a discharge shunt circuit, the VOUT pin is set to the
VSS level through several hundred k
Ω internal divided resistors between the VOUT pin and the VSS pin. The
S-19244xxxH Series A / B / E / F type allows the VOUT pin to reach the VSS level rapidly due to the discharge shunt
circuit.

5. Pull-down resistor (S-19244xxxH Series A / C / E / G type)
The ON / OFF pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS
level.
Note that the IC's current consumption increases as much as current flows into the pull-down resistor of
4.0 M
Ω typ. when the ON / OFF pin is connected to the VIN pin.
