A self-setting power supply monitors a supply current drawn by a power amplifier and sets a supply voltage based on the supply current to achieve efficient power operation. In order to maintain operation of the power amplifier above minimum operating conditions, the self-setting power supply sets the supply voltage to the minimum operating voltage when the supply current drops below a threshold bias current. When the supply current is above the threshold bias current, the self-setting power supply adjusts the supply voltage approximately proportionally to the supply current to maintain approximately constant gain of the power amplifier.
