ABSTRACT:
A method and apparatus for providing a regulated output voltage when supplied with an unregulated input voltage utilizes a detection circuit to selectively steer current between two current paths in order to minimize the amount of power dissipated by a pass device such as a bipolar transistor, MOS transistors, field effect transistors or other current control device.
