Abstract: A voltage regulator circuit is disclosed. The voltage regulator includes a feedback circuit configured to generate a feedback signal based on a voltage level present on a regulated power supply node. A comparison circuit is arranged to generate an error signal based on the feedback signal and a reference voltage level. A compensation circuit is configured to modify the error signal, based on a routing impedance coupled between the regulated supply voltage node and a load circuit, to generate a control circuit. An output circuit of the voltage regulator is configured to source current to the regulated power supply node based on the control signal.
