| Depends what that extra section of circuitry is, but could you simply

I would consider DC-DC converter modules for this - maybe not the cheapest option, and they are switching, but they are compact and easy.
I have used this sort of thing with no problem from HF noise but some people don't like switched mode supplies (ymmv).
