1. An adjustable power control module comprises:

  • a supply voltage comparison circuit operably coupled to compare a supply voltage with a low power threshold, wherein the supply voltage comparison circuit provides a low power indication when the supply voltage compares unfavorably with the low power threshold;

    a signal dependent current source operably coupled to provide a regulated current, wherein the signal dependent current source provides a first regulated current when the low power indication indicates the unfavorable comparison and provides a second regulated current when the low power indication indicates a favorable comparison; and

    power regulation module operably coupled to the signal dependent current source and to a circuit, wherein the power regulation module regulates power consumption of the circuit in accordance with the first or second regulated currents.
