摘要： A voltage regulator includes a first multi-gate transistor, a differential stage, a second stage having a second multi-gate transistor, and a pass transistor to apply an output voltage and output current to a device load. Based on a feedback voltage associated with the output voltage, the differential stage modulates a bias voltage applied to a control electrode of the pass transistor. A first gate of the second multi-gate transistor generates a nominal bias current for the pass transistor, and the second gate adjusts the bias voltage based on an output of the differential stage so that transients in the regulator output voltage resulting from sudden changes in current drawn by the device load are reduced.

摘要： A linear voltage regulator includes a first transistor, a feedback circuit, and a control circuit. The first transistor includes a first terminal coupled to an input terminal of the regulator, a second terminal coupled to an output terminal of the regulator, and a control terminal. The first transistor is configured to provide a load current to the output terminal at a desired voltage level based on a control signal on the control terminal. The feedback circuit is coupled to the output terminal and is configured to generate a feedback signal based on an actual voltage level at the output terminal. The control circuit is configured to provide, based on the feedback signal, the control signal at a level to substantially maintain an output voltage at the output terminal at the desired voltage level. An operating current of the control circuit is configured to increase, by a limited amount, responsive to a transient increase in the load current.
