Abstract: A switching regulator including a first converting stage and a second converting stage may be provided. The first converting stage may include a first output capacitor connected between a first output node and ground, the first converting stage configured to receive a first input voltage and provide an output voltage by adjusting a level of the output voltage based on a first dynamic voltage scaling (DVS) rate relating to a first load condition of a processing circuit. The second converting stage may include a second output capacitor connected between a second output node and the ground, the second converting stage configured to receive a second input voltage and provide the output voltage by adjusting the level of the output voltage based on a second DVS rate relating to a second load condition of the processing circuit, which is heavier than the first load condition of the processing circuit.
