A regulator is a device or a person that controls or manages something to keep it from becoming too much or too little. For example, a thermostat regulates the temperature in a room by turning on and off the heating or cooling system to keep the temperature at a comfortable level. A government agency such as the FDA can also act as a regulator by setting rules and standards for the safety and efficacy of drugs and medical products. In short, a regulator is something or someone that keeps things under control.
