In Reply to: Re: UPC 78M05 HF?(DATA?)168 degrees! I think I do need a higher current voltage regulator. posted by Mike Stehr on February 23, 2001 at 20:31:36:
Apparently a typical 78M05 can operate to a temp. of 150 deg. C, or ~300 deg. F. So you should be OK, but the cooler the better. Replacing the M version with a higher current rating plain 7805 (and still using the heat sink) would help. Yes, I meant Radio Shack by RS. I personally wouldn't buy electronic parts there except in an emergency, and wasn't recommending it, just using it as an example of how ubiquitous the 7805 is. Actually, that should be "was", since not too many people make them any more. Is the 7805 blown? I have tons of 7805's, all graded to voltage output, and can send you one if you want.
