[sci.electronics] 12V to 5V DC conversion, mounting TO-3 cans

gt1998b@prism.gatech.EDU (HOLLABAUGH) (07/13/90)

Folks,

Before you go to elaborate mounting schemes for your
TO-3 cans, check the internal connection to the TO-3 case.

The case might be the output voltage, which always sucks
(but is understandable).

it's aggrevating having to insulate your heat sinks from ground.

The 78Hxx series uses the case as ground.  Makes life easier for all of us.

I presume you meant insulate your heatsink from your device.

Nothing like grabbing a hold of a hot (thermal) hot (voltage) sink! :-)
