A current-to-voltage conversion circuit used in a digital isolator. The current-to-voltage conversion circuit has an input terminal to receive an input current, an output terminal to output a power supply voltage generated based on the input current. The current-to-voltage conversion circuit has an operational amplifier and a voltage regulation switch device, the voltage regulation switch device has a control end coupled to an output end of the operational amplifier. When the input current is less than an adjustment threshold, the voltage regulation switch device is turned off, and when the input current is greater than the adjustment threshold, the voltage regulation switch device is turned on.
