In the multichip module and shutdown method thereof, there are provided a semiconductor chip for voltage regulation which shuts itself down at a first setup temperature and a semiconductor chip for amplifier which is disposed in a common package together with the semiconductor chip for voltage regulation and shuts itself down at a second setup temperature. The semiconductor chip for voltage regulation is provided with means for outputting via a bus a signal for compulsorily shutting down the semiconductor chip for amplifier when the semiconductor chip for voltage regulation reaches a third setup temperature lower than the first setup temperature.
