Hi all, was hoping someone could answer a question about the 7912 I have used in my power supply. The pin out for the 7912 is
Ground, vin, vout, basically should there be continuity between vin and the metal tab on reverse of regulator? Doesn't seem ok to me as this will cause a short to any metal it comes in contact with. I think there is an insulating washer that goes on back of metal tab when heatsinking, but should it really be live?
Also Included pic of voltage reg, maybe someone could tell me if it is a descent brand or a dud, thanks..
