ABSTRACT:
An electronic device (102) includes a power supply (114), an amplifier circuit (132), and a power down protection circuit (160). The power supply (114) supplies power to the electronic device (102). The amplifier circuit (132) is powered by the power supply (114) to amplify a signal into an amplified output signal and controllable to vary a power level of the amplified output signal. The power down protection circuit (160) is coupled directly to the power supply (114) to lower the power level of the amplified output signal of the amplifier circuit (132) when the power supply (114) falls below a threshold.
