Hi All !!

I have a wireless button cam that has got a bad connector so thought I would replace it but when i took it apart it has a part that looks like a transistor in line to the 8v power suply. the part number is UTC78005AL.......does any body know of a replacment?

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?

PS

There was a femail jack attached before the part in question...

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 ?

ME!!

The femail jack end metal piece... I pulled the male adaptor out it came off with it!
then in an atempt to fix it I used my pliers to cut the left over off and to my horror SNAP lol.........oops...

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.

Any way to by pass?

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.)

Im gonna give it a test tomorrow after re-soldering the wires....however the reg has a nice crack in it...will let you guys know many thanks....

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