Abstract: An integrated circuit device has a digital device (600) operating at an internal core voltage (Vint); a linear voltage regulator (510); and an internal switched mode voltage regulator (180) controlled by the digital device and receiving an external supply voltage (Vext) being higher than the internal core voltage through at least first and second external pins (140a, 140b) and generating the internal core voltage, wherein the internal switched mode voltage regulator is coupled with at least one external component (182) through at least one further external pin (140c) of the plurality of external pins.
