A device for adjusting a set-down voltage according to the temperature variation of a plasma display panel(PDP) is provided to stably drive the PDP at a low temperature by changing the slope of a falling ramp wave according to the temperature of the PDP. A device for adjusting a set-down voltage according to the temperature variation of a plasma display panel includes a set-down voltage signal generator, a set-down voltage comparator(320), and a scan driver. The set-down voltage signal generator supplies a reset-down pulse to a first sustain electrode during a set-down of a reset period. The set-down voltage comparator detects the reset-down pulse voltage from the set-down signal generator, compares the reset-down pulse voltage with a predetermined reference voltage, and applies a scan driving control signal. The scan driver performs an address discharge in response to the scan driving control signal from the set-down voltage comparator. The set-down voltage comparator changes the slope of the falling ramp pulse according to the variation of the PDP.
