<R08>v: Electrical components that are not specifically allowed by the rules (i.e. sensors, batteries, microprocessors, etc.) are not permitted. Note that Microprocessors may be used only when connected thru the HiTechnic SuperPro Prototype Board or the NXT Prototype Board.

I did not see anything about voltage regulators throughout the rules, so in my opinion, no they are not, you can ask just to double check though. Distribution boards such as the RIGrunner are legal though.
