This device (14) for stabilising a microcircuit supply voltage (Vst) comprises a stabilising capacitor (Chv, Cpp) biassed by a voltage (Vhv, Vpp) higher than the supply voltage (Vst), and at least one switching means (17) for connecting the stabilising capacitor (Chv, Cpp) with an internal supply line (15) of the microcircuit when the supply voltage (Vst) is lower than a predetermined threshold (Vmin). The advantage which the invention brings is to enable a reduction of the silicon surface required for the stabilising capacitor. The invention is useful for silicon integrated circuits, in particular smart card or electronic label microcircuits.
