Disclosed herein is a protection circuit for a power amplifier. The protection circuit comprises a current detecting section for detecting a level of a load current of the power amplifier, a voltage detecting section for detecting a level of a load voltage across a load, an AND-gate circuit responsive to outputs of the current detecting section and the voltage detecting section for detecting a short-circuit of the load, and a control section responsive to an output of the AND-gate circuit for disconnecting the load from the amplifier.
