Abstract: PURPOSE: A video power regulation circuit of a VCD(video compact disk) player is provided to supply regular video power to a video output unit all the times even though main power is changed by motor noise when a user tracks up/down or searches up/down an audio CD or VCD. CONSTITUTION: Main power is changed by motor noise when a user tracks up/down or searches up/down an audio CD or VCD.

Herein, the two serial diodes are connected reversely to a 5V terminal of a power regulator(60). Therefore, the surge voltage is removed and the video output unit keeps input voltage regular. In addition, a capacitor(C2) compensates the input voltage of the video output unit to regular standard voltage when the voltage falls down lower than 5V or becomes unstable by the variable main power. Thus, the video output unit keeps the input voltage regular all the times.
