    摘要: A voltage regulator includes an amplifier and a regulation loop. The regulator includes a first PMOS transistor connected to a terminal supplying an input voltage, a second PMOS transistor connected in series with the first PMOS transistor. A node between those two transistors defines an output terminal. A first source of a first polarization current of fixed value is connected to the gate of the first transistor, and a second source of a second polarization current of fixed value connects the second transistor to ground. A third NMOS transistor is connected between the two current sources. A circuit is provided to modify automatically at least one of the polarization currents in relation to the load current.
