Ultralow Noise Regulators
Analog Devices offers a unique family of ultralow noise linear and switching regulators for applications that have severe noise requirements—for example, sensitive RF or audio circuits in a confined environment. These regulators are offered in step-up, step-down, inverting, flyback, and Ćuk topologies. Noise levels are typically in the tens of microvolts.
