A system for preventing power amplifier supply voltage saturation includes a multiple stage voltage regulator configured to provide a regulated voltage, a power amplifier configured to receive the regulated voltage, and a saturation protection circuit configured to apply a current into a first stage of the multiple stage voltage regulator when the regulated voltage reaches a reference voltage, the applied current causing a subsequent stage of the multiple stage voltage regulator to prevent the regulated voltage from exceeding the reference voltage.
