Abstract
Power supply regulators, integrated circuits including a power supply regulator, and methods of regulating a power supply are provided. In one embodiment, a power supply regulator includes a first self-bias circuit configured to receive a supply voltage from a power supply, a second self-bias circuit coupled to a reference voltage, and a clamping circuit coupled between the first and second self-bias circuits. The clamping circuit includes a NMOS transistor coupled to the first self-bias circuit and a PMOS transistor coupled to the second self-bias circuit. The clamping circuit is further configured to generate an output voltage less than the supply voltage at substantially the same time as when the supply voltage is received from the power supply.
