1. A power supply, comprising:

  • a) an input capacitor coupled to an input terminal, said input terminal being coupled to a power source, said power source providing energy that is constrained by a predetermined limit of said power source;

    b) an output capacitor coupled to an output terminal, said output terminal being coupled to a load, wherein said load is detected as being in a first load condition or a second load condition;

    c) a first regulator configured to convert an input voltage at said input terminal to directly regulate an output voltage at said output terminal to power said load;

    d) a second regulator coupled between said first regulator and an energy storage element, wherein said second regulator is configured to deliver energy from said energy storage element to said first regulator to maintain regulation of said output voltage at said output terminal when said second load condition is detected; and

    e) a third regulator coupled between said first regulator and said energy storage element, wherein said third regulator is configured to deliver energy from said first regulator to said energy storage element when said first load condition is detected.
