■ STANDARD APPLICATION EXAMPLES
* This NJM2930 is required when the mounting position is separated from the power filter.
** Use an aluminum electrolytic capacitor or a tantalum capacitor as C
2
. The temperature guarantee range of
capacitors should be down to -30°C. A capacity value of 10µF is a minimum requirement for improving the stability
and transient response. Mount it at a position as close to the leads as possible.
*** When application on automobile car operation, the minus pulse might
be input on IC. In this case, however, the pulse might trigger to latch up.
If it were that, this kind of latching up might be continued, the IC would
burn up into defective in many cases. It is advisable to apply D1, D2
as described in the drawing, in order to prevent from making any
troubles. It is important to make devices D1, D2 against V
IN
to be able
to stand for brake down voltage, current volume, and then less volume
for Vf.
