up the conventional way as shown in Figure 19. No damage
to the part will occur. The part also endures a short to battery
when powered by an isolated supply at a lower voltage as in
OUT
** C2 is required for stability.
*** C3 is recommended for EMC susceptibility.
The NCV8184 will survive a short to battery when hooked
* C1 is required if the regulator is far from the power source filter.
