All integrated voltage regulators I've seen are noisy. If you want a quiet regulator, you'll have to construct it yourself. One good topology would be a well-filtered Zener driving a darlington power transistor (or driving a high-gain TO-92 to an emitter follower). Another is a standard opamp with a reference on its non-inverting input and feedback to its inverting input from an output transistor. Either of these will exhibit a noise level that is orders of magnitude less than what's produced in any device employing thermionic emission.
