The invention proposes a low-dropout voltage regulator comprising an output terminal for providing an output voltage (Vout) regulated as a function of a reference voltage, and for providing an output current (Iout), and additionally comprising an output current limiting unit (LIMIT3), with said unit comprising:—replication means for replicating the output current (T31) to provide a mirror current of the output current (Imirror),—comparison means (COMP31, COMP32) for comparing the mirror current with a reference current (Iref),—feedback means for supplying feedback (COMP31, COMP32, R35, REGUL3) to the regulator in order to limit the output current when the mirror current is greater than the reference current, and the mirror current is injected into the output terminal. |
