Abstract
Disclosed is a voltage regulator having input terminals for connection to a voltage supply, output terminals for supplying power to a circuit at a predetermined maximum supply voltage, and a voltage regulator circuit connecting the input and output terminals. The voltage regulator circuit has a first supply path connecting first input and output terminals, a second supply path connecting the other input and output terminals, and an active component arranged between the first input and output terminals. A feedback control loop connected to a control terminal of the active component is arranged to sense the voltage on the output side of the active component and, when the voltage is above the maximum supply voltage, limit the output voltage to the maximum supply voltage, and, when the voltage is below the maximum supply voltage, signal the active component to pass power from the input terminals to the output terminals.
