Abstract
Provided is a power supply circuit that supplies power to a load, including a power supply section that outputs a power supply current, a driver section that receives the power supply current from the power supply section and supplies the load with a load current that is consumed by the load, a capacitor section that is charged by the power supply section and that supplies the driver section with an auxiliary current when the load current is greater than the power supply current, and a transmission path that transmits the power supply current output by the power supply section to the driver section, wherein the capacitor section is disposed between the transmission path and a reference potential. The capacitor section is disposed between a transmission path and a reference potential. Also provided is a test apparatus including the power supply circuit.
