8. External part list and description
(Precaution 1)
When the stand−by terminal was put to the low level after the ripple rapid discharging circuit was operated
(V
the stand−by terminal low shall be set at 8V or above so that (1) the stand−by terminal is put at the low level
and (2) the ripple rapid discharging circuit is turned on when V
example of application is shown in Fig.9.
(Precaution 2)
If the falling time constant of the V
In this case, it is possible to prevent the pop noise from becoming worse by reducing the ability of “ripple rapid
discharging circuit at the time of V
However, it shall be kept in mind that the time for turning the power on becomes longer as the result of this
method.
