An integrated circuit includes: a power supply circuit configured to generate a supply voltage from at least one of first and second power source voltages; and a system load that operates by receiving the supply voltage through an output node of the power supply circuit. The power supply circuit includes a first low drop-output (LDO) regulator that generates, from the first power source voltage, a first load current flowing to the system load through the output node; and a second LDO regulator that selectively generates a second load current flowing to the system load through the output node, from the second power source voltage based on a difference between voltages of internal nodes of the first LDO regulator.
