Linear voltage regulators and associated methods

Abstract:

A linear voltage regulator includes a series-pass element electrically coupled between an input node and an output node, current sense circuitry configured to generate a current sense signal representing at least magnitude of current flowing through the series-pass element, and control circuitry. The control circuitry is configured to control the series-pass element according to at least (a) the current sense signal and (b) a voltage sense signal representing magnitude of an output voltage, to clamp the magnitude of the output voltage to a maximum value, where the output voltage is a voltage at the output node, such that the magnitude of the output voltage decreases with increasing magnitude of current flowing through the series-pass element.
