Analog Devices Inc. LT8627SP Synchronous Step-Down Regulators
Analog Devices Inc. LT8627SP Synchronous Step-Down Regulators use third-generation Silent Switcher technology, which combines an ultralow-noise reference with Silent Switcher architecture. This design achieves high efficiency and excellent wideband noise performance. The LT8627SP regulators' ultralow-noise architecture ensures exceptional low-frequency (0.1Hz to 100kHz) output noise performance in a switching regulator. Additionally, the output voltage can be set with a single resistor, maintaining nearly constant output noise regardless of the output voltage setting.
