The invention discloses a multi-output-mode power supply circuit and test equipment. The multi-output-mode power supply circuit comprises a signal generation module, a power amplification module, a feedback resistance module and a feedback resistance switching control module. The signal generation module outputs a voltage control signal through a first output end, and outputs a driving signal through a second output end; the power amplification module is used for performing current amplification or voltage amplification according to a voltage control signal of a first input end of the power amplification module; the feedback resistor module is used for connecting a feedback resistor to the power amplification module, and the feedback resistor switching control module is used for controlling switching of the feedback resistor in the feedback resistor module according to a received driving signal and controlling the power amplification module to work in a current amplification mode or a voltage amplification mo
