Integrated circuit for tuner

Abstract

Abstract PURPOSE:To attain a stable overall characteristic by providing a stabilized voltage output terminal leading to a voltage stabilizing circuit. CONSTITUTION:The stabilized voltage output terminal 24 able to output a stabilized voltage from a voltage stabilizing circuit 10 is provided to a tuner integrated circuit 23 having a mixed circuit 4, an oscillation circuit 6, an IF amplifier circuit 7 and the voltage stabilizing circuit 10. Thus, each circuit in the tuner integrated circuit 23 is operated by a stabilized voltage supplied from the voltage stabilizing circuit 10, operated very stably against the fluctuation of the voltage for driving the tuner integrated circuit or the change in the ambient temperature and a stabilized voltage is supplied from the stabilized voltage output terminal 24 of the voltage stabilizing circuit 10 to the circuit section at the outside of the tuner integrated circuit 23.
