1. A voltage regulator comprising:
a differential amplifier having a first input configured to receive a reference voltage and a second input configured to receive a regulated voltage output signal from an output node via a feedback circuit;
an intermediate node between an output of the differential amplifier and the output node;
a load stage coupled between the output node and a first power supply node; and
a compensation stage coupled between a second power supply node and the intermediate node, the load stage responsive to a boost control signal and the compensation stage responsive to a complementary boost control signal.
