Abstract
A voltage regulator circuit is provided, which includes a main regulator and at least one auxiliary regulator. The main regulator provides an output voltage and regulates the output voltage according to the output voltage and a reference voltage. Each auxiliary regulator is coupled to the main regulator. Each auxiliary regulator also provides the output voltage and regulates the output voltage according to the output voltage and the reference voltage. Each of the main regulator and the at least one auxiliary regulator provides a branch current of the same magnitude. An output current of the voltage regulator circuit includes the branch currents provided by the main regulator and the at least one auxiliary regulator.
