In one embodiment, an apparatus includes a voltage regulator, an amplifier, and control logic. The regulator may receive a supply voltage and output a regulated voltage to an intermediate node. In turn, the amplifier is to be powered by the regulated voltage, while the control logic is coupled to the voltage regulator to cause a change in the regulated voltage to a safe voltage before one or more gain stages of the amplifier is to be coupled to or decoupled from an output signal path.
