Embodiments of the invention are generally directed to a linear regulator with improved power supply ripple rejection. An embodiment of an apparatus includes an linear regulator to receive a system power supply and to generate a regulated power supply; a first voltage reference generator to generate a first voltage reference for the linear regulator; a second voltage reference generator to generate a second voltage reference for the linear regulator; and a voltage reference and power switcher. In some embodiments, the voltage reference and power switcher is to switch a voltage reference for the linear regulator from the first voltage reference to the second voltage reference and is to switch a part of a power supply for the linear regulator from the system power supply to the regulated power supply.
