    317's are beautiful. If you overload them they shut down. If you overheat them they shut down. This allows them to be an over temp protector for anything on the same heatsink. They don't see the full voltage they regulate so they can regulate quite high voltage. The can be found for less than a $1.00. They are quite marvelous.
