You might contact DimensionEngineering and ask if the regulator is suitable for use on a motorcycle. Aside from crossing your fingers and hoping it works it'd be the best way to find out. Also, since you seem to have enough space on the board, it wouldn't hurt to add a couple places for caps on both sides of that regulator as if you were using a typical linear regulator. You've got a fall back position then.
Yes, you're so right, crossing your fingers and hoping is something I really don't want to do! And there is nothing to learn from it except trail and error. I contacted DimensionEngineering and I got a very quick response (within 2 hours):
"No problem! We have lot of those in use in cars/motorcycles. What's nice about the units in that application is they already have capacitors on the input and output... No need for further filtering."
I guess this solves this issue now. Thanks for the help on this
Yes. Try to keep those caps as close to the IC as possible. Again after testing your board you might not find them necessary ... but you've got that fallback position.
Once again thanks, no thank you a thousand time
I will put the capacitors as close as possible. When I did my redesign I will post the new PCB files here. I hope you have some time by then to watch it.
