Abstract
Described embodiments provide for a regulated voltage supply to a Universal Serial Bus (USB) system. The regulator comprises a pass device that might be coupled to a host device providing a bus voltage. An integrated USB physical layer (PHY) is coupled to the pass device through a control voltage signal pin. A regulation circuit is coupled to the integrated USB PHY, and the regulation circuit supplies about 3.3V from the bus voltage.
