The temperature sensor measures temperatures within a defined temperature measuring range. The sensor includes a reference voltage source with an output terminal to which a reference voltage is applied and which is connected to a first input terminal of a comparator. A series circuit of a semiconductor component with temperature-independent current characteristic and a reference component is connected between a first and a second supply voltage terminal. A temperature-dependent voltage is applied to a node common to the semiconductor component and the reference component. The temperature-dependent voltage is fed to a second input terminal of the comparator. The supply voltage is adjustable within a defined supply voltage range and, within a voltage range resulting from the supply voltage range of a voltage across the reference component, the reference component has a voltage-dependent current characteristic.
