Embodiments of power amplification devices are described with a power amplification circuit that has more than one amplifier stage and with at least a first voltage regulation circuit and a second voltage regulation circuit configured that provide regulated voltages to these amplifier stages. The power amplification device includes a threshold detection circuit to get better maximum output power performance while preserving power efficiency. The threshold detection circuit is configured to increase a first voltage adjustment gain of the first voltage regulation circuit when a regulated voltage level of a second voltage regulation circuit reaches a first threshold voltage level. In this manner, the first voltage adjustment gain can be initially set to be lower than the second voltage adjustment gain until the second voltage regulation circuit is close or has railed. The first voltage adjustment gain can then be increased to allow the first voltage regulation circuit to also rail.
