Abstract:
1. A voltage regulator comprising: a regulating transistor having a first current electrode for providing a regulated voltage, a second current electrode, and a control electrode; and a control circuit having an output coupled to the control electrode of the regulating transistor, and an input coupled to the first current electrode of the regulating transistor, the control circuit comprising a first inverting gain stage having a first load element, and a second inverting gain stage having a second load element, wherein one of the first load element or the second load element is characterized as being a diode and the other of the first load element or the second load element is biased by a bias circuit, wherein one of the first inverting gain stage or the second inverting gain stage includes an input transistor that includes a control electrode coupled to the first current electrode of the regulating transistor, wherein the regulating transistor and the input transistor are of a same channel conductivity type; wherein the bias circuit comprises:
