- If you are trying to regulate a 60 volt supply, the outboard
- components to protect the 3-terminal regulator are going to begin
- to become complex. It would probably be just as easy to use
- discrete components for the pass elements.
-
- Is there something inherently difficult in producing a regulator chip
- to regulate more than 40 volts?
- This seems to be the limit for regulators that I can get hold of
- through DIY electronics stores.
-
- What would be good is for a regulator that would regulate high voltages
- but switching the high currents through a power transistor.
- I have seen regulators like this but again they seem to go up to 40 volts
- only.
- A poster did send me the number of a TI chip to do this but I haven't seen
- it advertised over here.
-
- Does this style of regulator handle over current?
-
- I'm just curious that it is hard to get ready built regulators that
- will handle say +-80 volts at say 10 amps which is the sort of thing one
- needs for audio power amps.
- At least I haven't seen any.
