    Abstract: Voltage regulator circuitry, comprising: a pull-up path connected between a high-voltage supply and an output node for supplying a pull-up current from the high-voltage supply to the output node; a pull-down path connected between the output node and a low-voltage supply for drawing a pull-down current from the output node to the low-voltage supply; and a controller comprising pull-up control circuitry operable to control the pull-up current and pull-down control circuitry operable to control the pull-down current, so as to regulate an output voltage signal provided at the output node at a target voltage level even when an output current drawn from the output node along an output current path by a load varies over a range of positive and negative values, wherein the pull-down control circuitry is operable to: obtain measures of the pull-up current; and control the pull-down current based on the measures using at least one of proportional, integral and derivative control.
