Abstract:
A low-dropout voltage regulation device includes a power stage having an output terminal coupled to a load circuit, the load circuit being operable in a plurality of operating modes. The load circuit is configured to receive a different respective output current when in each of the plurality of operating modes. An error amplifier has an output coupled to an input terminal of the power stage. A compensation circuit is coupled to the input terminal of the power stage and is operable in a plurality of selectable configurations that are respectively tailored to the plurality of operating modes. The plurality of selectable configurations are selectable in response to a control signal representative of a current operating mode of the load circuit.
