    Hi
    welcome to the forums :)


    it could be a 5V voltage regulator

    can you do a sharp closeup pic of the unit and device please?

    First impression is a voltage regulator for the attached cmos module, if it is, would it be posative or a negative regulator, tricky, have you tried looking for a schematic, or the part ? i would think posative, what happened to the fixing tab ?

    Yes ive had an occasional oh oopp's moments, not often thankfully.
    But the replacement must be the same part and case type, what looked like a TO220 case, maybe, the new part might have slightly different writing on it, so long as the part is the same there wont be additional problems.

    A diagram or schematic will speed up the process.

    That picture says 78D05AL, not 78005... It's just a surface mount (TO-252) version of the ordinary 7805 (TO-220) regulator, 5V 1A, 2V dropout voltage.
    It looks horrible but I'm not so sure it's broken, except for the yellow wire. The tab is supposed to be that short.
    It seems that white = +7-12V input (from adapter), black = ground/negative, yellow = +5V output (to cam.)

    Yes, zooming in on the first picture reveals there are probably fatal damages to it..
