Analog Devices Inc. LT®8625S Synchronous Step-Down Regulators

Analog Devices Inc. LT®8625S Synchronous Step-Down Regulators use third-generation Silent Switcher technology. This technology integrates an ultralow-noise reference with Silent Switcher architecture, ensuring high efficiency and excellent wideband noise performance. The innovative design of Analog Devices Inc. LT8625S regulators delivers exceptional low-frequency (0.1Hz to 100kHz) output noise performance in a switching regulator. The output voltage is programmable with a single resistor, maintaining virtually constant output noise regardless of the output voltage setting.
