    Applicant: ST MICROELECTRONICS SRL ,  CONS RIC MICROELETTRONICA

    Inventor： URSINO RICCARDO ,  GARIBOLDI ROBERTO

    IPC: G05F1/575 ,  G05F1/00

    Abstract: The invention relates to a voltage regulator connected between first (VS) and second (GND) voltage references and having an output terminal (O1) for delivering a regulated output voltage (Vout), which voltage regulator comprises at least one voltage divider (11), connected between the output terminal (O1) and the second voltage reference (GND), and a serial output element (18) connected between the output terminal (O1) and the first voltage reference (VS), the voltage divider (11) being connected to the serial output element (18) by a first conduction path which includes at least one error amplifier (EA) of the regulated output voltage (Vout) whose output is connected to at least one driver (DR) for turning off the serial output element (18), the voltage regulator comprising, between the voltage divider (11) and the serial output element (18), at least a second conduction path for turning off the serial output element (18) according to the value of the regulated output voltage (Vout), in advance of the action of the first conduction path. The invention also concerns a method of turning off a serial output element (18) as a regulated output voltage (Vout) from a voltage regulator (10) changes.
