A compensation circuit is added to introduce a zero that tracks the voltage regulator's non-dominant pole. The compensation circuit includes a compensation transistor, whose gate is connected to receive the same voltage as the regulator's load driving pass transistor, and a series combination of a capacitance and a tracking resistance connected in series between the compensation transistor's gate and a supply level, where the value of the tracking resistance depends on the current supplied to the load. The tracking resistance can be implemented as a diode connected NMOS through which the compensation transistor is connected to the low supply level, or a diode connected PMOS whose current tracks that of the compensation transistor through a current mirror.
