    • Embodiments for at least one method and apparatus of a multi-use voltage regulator providing a supply voltage to a power amplifier and at least one other device are disclosed. One method includes generating a plurality of regulated voltage supplies from an unregulated voltage. An output signal power level of the power amplifier is determined. A one of the regulated plurality of voltage supplies and the unregulated voltage supply is selected as a power amplifier voltage supply for the power amplifier based at least in part on the output signal power level of the power amplifier. If the selected power amplifier voltage supply is one of the plurality of regulated voltage supplies, then the selected one of the plurality of regulated voltage supplies is simultaneously provided to the power amplifier and the at least one other device.
    • 公开了向功率放大器和至少一个其他设备提供电源电压的多用途电压调节器的至少一种方法和装置的实施例。 一种方法包括从未调节的电压产生多个调节电压源。 确定功率放大器的输出信号功率电平。 至少部分地基于功率放大器的输出信号功率电平,选择调节多个电压源和未稳压电源中的一个作为用于功率放大器的功率放大器电压源。 如果选择的功率放大器电压源是多个调节电压源中的一个,则将所选择的多个稳压电源中的一个同时提供给功率放大器和至少一个其他装置。
