摘要：
A voltage regulator includes an output stage including a control terminal and a load path, with the load path coupled between the input terminal and the output terminal. The voltage regulator also includes a control circuit with an input stage, a first current mirror, and a second current mirror. The input stage includes 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. The first current mirror includes 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 the pass device.
