Abstract: An electronic device includes: a switching regulator configured to generate a conversion voltage with respect to an input voltage, based on a switching signal of a first frequency, and output the conversion voltage; a stabilization circuit including a capacitor element connected to a load device via a first node and configured to generate a load voltage by stabilizing the conversion voltage by using the capacitor element and output the load voltage to the load device; a frequency sensing circuit configured to sense a frequency of the load voltage and output sensing information about the frequency of the load voltage; and a frequency booster circuit configured to form a first current path connected to the first node, based on the sensing information.
