*1. Connect a capacitor between the SSC pin and the VSS pin.
The inrush current limit time of the VOUT pin at power-on or at
the time when the ON / OFF pin is set to ON can be adjusted
according to the capacitance.
Moreover, the SSC pin is available even when it is open.
For details, refer to " Selection of Capacitor for Inrush
Current Limit (C_SS) (Types in Which Output Voltage is
Internally Set of HSOP-8A, HSOP-6, SOT-89-5)".
