Abstract
A voltage regulator includes a regulating transistor and a control circuit. The regulating transistor has a first current electrode for providing a regulated voltage, a second current electrode, and a control electrode. The control circuit has 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 includes a first inverting gain stage having a first load element, and a second inverting gain stage having a second load element. One of the first or second load elements is characterized as being a diode and the other of the first or second load elements is biased by a bias circuit.
