ABSTRACT:
A switching regulator includes a first switching element to perform a switching operation in accordance with a first control signal input thereto to control an output voltage based on an input voltage, a second switching element having a size smaller than the first switching element to perform a switching operation in accordance with one of the first control signal and a second control signal input thereto to control an output voltage based on the input voltage, and a control circuit to control the first and second switching elements to perform the switching operations in one of a normal operation mode and a light load operation mode in which a current consumed by a load connected to the switching regulator is smaller than a current consumed in the normal operation mode, and control the first switching element to be turned off in the light load operation mode.
