Abstract: The present invention is directed to prevent occurrence of a problem on a withstand voltage in a circuit group which receives supply of an internal power supply voltage. An error amplifier outputs a control voltage obtained by amplifying a difference voltage between a reference voltage and a divided voltage obtained by dividing an internal power supply voltage to an output node. A drive transistor supplies a drive current according to the control voltage of the output node of the error amplifier from an external power supply line to an internal power supply line. When the divided voltage exceeds a predetermined voltage, a clamp circuit changes the control voltage in the direction of decreasing the drive current.

Abstract: A differential amplifier circuit is connected to the input node and the output node of the final amplification stage through detection circuits. The signal level difference output from the differential amplifier circuit does not change even if the input power varies. Because a change in the power gain at the output node does not travel back to the input node when the load impedance of the wireless frequency power amplifier varies, it is possible to detect only the change in the load impedance. Damage to the final stage can be prevented by controlling the operating current of the final stage and the gain of the drive stage according to the detected load variation. Nonlinear distortion in the wireless frequency power amplifier output can also be reduced by detecting and canceling the change in the gain of the drive stage by changing the gain of the adjustment stage.
