I have been searching the internet to no avail. I am sure there used to be a high-voltage regulator IC that came in a TO-220 package, and would take 400V or maybe more on its input, but which is now obsolete. Kinda like an LR8 but bigger.
I think it was made by Texas, but I may have imagined that. Does anyone know the part I'm thinking of??
