Systems and methods for producing a substantially constant output voltage in a power source boost system are provided. A power supply boost circuit includes an output node for supplying an output voltage, a feed forward loop configured to be coupled to a load and a power source, and a feedback loop including a voltage limiter coupled to the feed forward loop and the output node. One power source boost system includes the above power source boost coupled to a load and a power source. A method includes the steps of comparing, via a feedback loop, a constant voltage to a reference voltage, and stabilizing a power source boost system over a range of input voltages and load variations. The stabilizing step includes the step of limiting, via a limiter, a voltage supplied to a feed forward loop to a predetermined range of voltages based on the comparing step.
