We present a low dropout voltage regulator which uses a regulated replica in the loop in order to achieve small area, excellent power supply rejection over a wide frequency range, and high loop stability. The regulated replica provides accurate matching of the gm/gds ratio in the current source transistors for the replica and the load path. Power supply rejection of >22dB was measured up to lGHz for a circuit operating at 0.8V from a 1.0V supply.© 2008 IEEE.
