Any chance you recall the brand you used?
I would just use a lm7805 for less than a buck.
Well, I'll be! That looks like the ticket. Thank you.
Not if you mount it on a good enough "heat sink" and are not drawing full rated power from it. The DROK unit I have goes from 12v down to 2.1v and it has worked for over 100hrs with with no problems. Now, I have mine mounted on one of the aluminum angles that braces the instrument panel which acts like a giant "heat sink". That, combined with the DROK packaging, is more than adequate even during the hot Florida summers.Thank you for that info. Looks like 12 volts "in" is way too much for this.
