1. A multi-phase switching regulator, comprising:
a first regulating circuit configured to receive an input voltage and to output a first sub-output voltage with a first phase to a first output node by transforming the input voltage;
a second regulating circuit configured to receive the input voltage and to output a second sub-output voltage with a second phase to a second output node by transforming the input voltage;
a first current sensor configured to sense a first current flowing in the first output node;
a second current sensor configured to sense a second current flowing in the second output node; and
a current balancer configured to receive the first current and the second current and to output a current control signal to the second regulating circuit based on a first sensing value of the first current and a second sensing value of the second current, and
wherein the second regulating circuit adjusts a second current level of the second current to be equal to a first current level of the first current based on the current control signal.
