An overshoot suppression circuit comprises a switch for coupling to an
output of a voltage regulation module and a voltage detector for
detecting an output voltage at the output. When the load to the voltage
regulation module changes from heavy to light to result in the output
voltage higher than a threshold, the voltage detector turns on the switch
to release energy from the output, and thereby the output voltage is
suppressed to produce overshoot to damage the load coupled to the output.
