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.. -Steve Gregory- --------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
