Subject: [TN] Part Marking Question...

Hi All!

Got a part marking question that maybe somebody help me with. I've got two regulators, a negative 12V part, and a positive 12V part.

The positive 12V part is supposed to be a Motorola MC78M12CDT, a 12V, 0.5A, 4% regulator. The part we have is marked 78M12RV122...no logo or anything that identifies the manufacturer.

The negative 12V part is supposed to be a Motorola MC78M12CDT, a -12V, .05A regulator. The part is marked 78M12RV122, same thing, no logo either...

I've searched and searched to try and link the part markings to a manufacturer or description of what these parts really are, but no luck. The distributor hasn't been very helpful either.

Thanks in advance..
