[Id the IC]

I am trying to come up with an id on these chips in
order to retain a datasheet so far I’ve come up empty
handed.

[Component identity]

There is a transistor right beside it.
There is print on the board that identifies the
junctions as E-C-B. This on the other hand lables
the terminals I -G-O Input guround and output.
so Im fairly certain it is a regulator. I just need
to find out what  voltage it is The numbers I gave
you are correct however there is a chance the part
has been relabled. I know this because I found some other
components where Im positive that this was the case. However
Im not sure with this one. The only thing I do know is that it is
a TO-92 case regulator with the numbers I listed in the first post.
If you're unable to find anything with those numbers I stongly
suspect that this one has been relabled also. If so then there
is not much that anyone will be able to do.

Thanks for your time.

I have a 3 pin regulator and have not had any luck
comming up with an exact description of the part.

All that Ive been able to establish is that it was made
by National Semiconductor (it has thier logo)
I checked thier website but came up empty handed.
It is a TO92 case. the number layout is as follows.

National
semiconductor  105    (theres a line over top the first two digits)
logo here                 
     
            CA  42
            33192

these are all the numbers that are on the device.

any help apreciated.
thanks.
