ABSTRACT:
A voltage regulator circuit is provided for a sensor that is connected in a two-wire scheme to a circuit comprising a power supply and a load. The circuit regulates the current flowing through the load when the sensor output is inactive and provides power to the sensor during periods of time when the input power of the regulator circuit is insufficient to do so. A current monitor and a voltage monitor are provided which utilize common circuit elements to control the current flowing through the circuit. The operational characteristics of a MOSFET device are used advantageously to control the magnitude of current flowing through the sensor and regulate the current as a function of both the magnitude of current and the magnitude of a voltage potential across a bulk capacitor.
