Worth giving a try.

Thanks
I have a .brd somewhere for a small 7135 board, made to slide over the diodes pins.
You could have osh park make you a few

As opposed to this:

http://s187.photobucket.com/user/bsh...c7135.jpg.html

Can someone explain what is going on HERE?

http://circuits.datasheetdir.com/38/...5-circuits.jpg

Is this possible to use and make it case negative with this?

Otherwise I need to isolate both the circuit and the case negative head (pain in the ...)

I ordered a couple dozen to try. They will work and be ultra cheap.

Its just acting as a current sink , there will be 350mA flowing though the diode and the regulator to ground + any supply current on the VDD pin to the regulator itself

Assuming the diode was case isolated then running the driver case ground would work fine .

Thats what I was afraid of. Case negative will bypass the driver entirely

Oh well. Thanks for the info.
