A fluid pressure regulator and method of regulating high pressure fluid from a container such as high pressure gas cylinder, compensate for variation in the supply pressure to the regulator to limit variation in the outlet pressure of the regulator due to supply pressure variations. A flexible valve seat of the regulator is mounted in the regulator so that the seat can flex in response to changes in the supply pressure to change the operating point of the valve seat concurrently with changes in the balance of forces on a diaphragm of the regulator caused by changes in the supply pressure to the regulator. Advantageously, the regulator and method eliminate the need for using two stage regulators for minimizing outlet pressure variations due to the supply pressure effect.
