Abstract:
1. A voltage regulator, comprising: an output terminal configured to provide an output voltage; an input terminal configured to provide an input voltage supply potential; an output stage comprising a control terminal and a load path, the load path coupled between the input terminal and the output terminal; and a control circuit comprising an input stage, a first current mirror, and a second current minor; wherein the input stage comprises a first control input configured to receive a first reference voltage, a second control input configured to receive a second reference voltage, a feedback input coupled to the output terminal, a first output terminal, and a second output terminal, wherein the first current mirror comprises a reference current path coupled between a first supply terminal and the first output terminal of the input stage, and an output current path coupled between the first supply terminal and the control terminal of a pass device, wherein the second current mirror comprises a reference current path coupled between a second supply terminal and the second output of the input stage, and an output current path coupled between the second supply terminal and the control terminal, and wherein the input stage is configured to control a current through the reference current path of the first current mirror dependent on a voltage between the first control input and the feedback input, and to control a current through the reference current path of the second current minor dependent on a voltage between the second control input and the feedback input.
