摘要
A circuit and method for producing an output voltage that replicates an input voltage. A circuit comprises an amplifier stage configured to amplify a difference between an input voltage and a feedback voltage. An output stage is configured to produce an output voltage equal to the input voltage. The output stage configured to be driven by the difference between the input voltage and the feedback voltage. The output stage further comprises a main supply current path configured to provide a first current from a main supply source, the first current providing at least a portion of the output voltage, and a current management circuit configured to provide a second current from an auxiliary supply source, the second current providing any remaining portion of the output voltage not provided by the first current.
