Voltage regulator circuit

摘要

A voltage regulator circuit includes a circuit input and a circuit output for coupling to a load. A circuit interrupt element is coupled between the input and the load for breaking the circuit between the input and the load. A sensing circuit coupled to the output senses when a signal applied to the load exceeds a defined limit. A trigger circuit coupled to the sensing circuit causes the circuit interrupt element to trip when the sensing circuit senses a signal which exceeds the defined limit.
