PROBLEM TO BE SOLVED: To provide a regulator power supply circuit capable of adjusting an output voltage according to a current being output to a load. SOLUTION: The regulator power supply circuit includes a power output portion for outputting output power to a succeeding stage side, by use of power being input from a preceding stage side, and a power control portion for detecting a voltage on the succeeding stage side of the power output portion, and for controlling the above output power so that the above detected voltage approaches a predetermined target voltage, thereby outputting the above output power to a predetermined load. The regulator power supply circuit further includes a target voltage adjustment portion for detecting the magnitude of the current which is output from the regulator power supply circuit to the above load, and for adjusting the above target voltage according to the above detection result.
