The application provides a voltage generating circuit and electronic equipment, comprising a bias current module, a response control module, a driving module, a threshold reduction module and an output voltage setting and sampling module, and has simple structure. The preset bias current input by the bias current module can control the transistor to work in a sub-threshold region, so that the circuit has low power consumption. The output voltage setting and sampling module can set the value of the target output voltage, improving the application flexibility of the circuit. The response control module can adjust the output current size generated by the driving module according to the sampling result output by the output voltage setting and sampling module, achieving the purpose of loop control of the current, which not only can ensure that the output voltage stability of the voltage generating circuit is high, but also can improve the dynamic response speed of the circuit. The threshold reduction module can control the driving module to work to provide the output current under the condition that the power supply voltage is lower, so that the voltage generating circuit has a wider input voltage range.
