The voltage monitoring circuit includes: an input terminal, applied with a monitoring target voltage or a divided voltage of the monitoring target voltage; a reference voltage generating circuit, generating a first reference voltage; a linear power circuit, converting the first reference voltage to a second reference voltage; a feedback resistor, generating a divided voltage of the second reference voltage, and negatively feeding back the divided voltage of the second reference voltage to the linear power circuit; and a comparing portion, comparing the second reference voltage with the monitoring target voltage or the divided voltage of the monitoring target voltage applied to the input terminal.
