It can be used generally to connote any set of various controls or devices for regulating or controlling items or objects.
Examples are a voltage regulator (which can be a transformer whose voltage ratio of transformation can be adjusted, or an electronic circuit that produces a defined voltage) and a fuel regulator (which controls the supply of fuel).
In social science, a regulator is an official responsible for control and supervision of an activity or area of public interest.
