After at least 30 ms has passed after the
standby OFF, please OFF SP Save.
The characteristics listed below are reference values based on the IC design and are not guaranteed.
The timing control of power-ON/OFF and each logic according to the procedure below should be recommended for the best pop performance
caused in switching.
It depends for this time on the capacity value linked to a standard voltage terminal (VREF), and the capacity value and resistance linked to
an input terminal (IN).
It is a recommendation value in a constant given in the example of an application circuit (block diagram).
