Abstract: This specification discloses methods and devices for limiting output current of a voltage regulator, in order to protect the voltage regulator against component overstress in case of output load current overloading. In some embodiments, a current limitation circuit acting on a reference input voltage of a voltage regulator can limit the maximum output load current of the voltage regulator. Once the current limitation circuit detects an over current load, the reference voltage is adjusted or decreased to limit the maximum output load current. Additionally, these methods and devices can be coupled easily with a slew rate control circuit to also limit the inrush current.
