Analog Devices offers a specialized family of ultralow-noise linear and switching regulators designed for applications with stringent noise requirements, such as sensitive RF or audio circuits in confined environments. This product family features a unity-gain current reference architecture that delivers a fast transient response and a high Power Supply Rejection Ratio (PSRR). The Silent Switcher 3 regulators are available in step-down topologies and can also be configured in inverted buck-boost (IBB) mode to power negative rails while maintaining exceptional low-noise performance. Ultralow-noise LDOs (low-dropout linear regulators) provide extremely low dropout, fast transient response, and excellent line and load regulation. Output voltages for both the switchers and LDOs can be dynamically adjusted by applying a DAC to the SET pin. The integrated RMS noise, measured from 10 Hz to 100 kHz, for these ultralow noise linear and switching regulators, is typically in the range of tens of microvolts or lower.
