Abstract
Methods for fabricating an integrated circuit with a voltage regulator are provided. In some implementations, a method includes forming a primary regulator on a semiconductor substrate, including fabricating a switch, fabricating an amplifier for controlling the switch, and fabricating a voltage generator for biasing the amplifier to operate the primary regulator in a bypass mode or in a regulating mode. The method further includes forming an input terminal and an output terminal of the primary regulator on the semiconductor substrate, forming a secondary regulator on the substrate, forming an input terminal and an output terminal of the secondary regulator on the semiconductor substrate, and forming an electrical connection between the output terminal of the primary regulator and the input terminal of the secondary regulator.
