A voltage reference circuit serves to furnish a reference voltage for an application-specific integrated circuit. The voltage reference circuit includes a voltage input for applying an operating voltage; a ground terminal; a voltage output for furnishing a reference voltage; and a signal output for furnishing a power-on reset signal. The voltage reference circuit includes an IPTAT circuit, connected between the voltage input and ground terminal, for generating a current proportional to the absolute temperature, the voltage reference circuit being embodied to furnish the power-on reset signal only if the reference voltage has reached a target value and if additionally a current is flowing in the IPTAT circuit with a quantity of current that reaches or exceeds a minimum current intensity determined by a voltage value of the operating voltage and by a pull-down resistance value.
