Title: Electromagnetic compatible regulator

Abstract: A voltage regulator circuit for providing a regulated output voltage at an output terminal, the regulator circuit including a current source (I.sub.control) including a current source MOSFET a current mirror circuit including a driver MOSFET (M.sub.1) and a follower MOSFET (M.sub.2) interposed between the current source and the output terminal, the current source and current mirror being operatively linked as to regulate an input voltage V.sub.in to the regulated output voltage, wherein the circuit further includes an EMC stabilising MOSFET having its drain connected to its substrate and placed in series with any of the driver or follower MOSFETs.
