LT83401/LT83402 Step-Down Regulators

Analog Devices LT83401/LT83402 Step-Down Regulators are developed to incorporate an ultra-low-noise reference with Silent Switcher® architecture. The combination achieves both high efficiency and exceptional wideband noise performance. The Silent Switcher ultra-low-noise architecture delivers superior low-frequency (0.1Hz to 100kHz) output noise performance in a switching regulator. The output voltage can be programmed with a single resistor, resulting in virtually constant output noise independent of output voltage. The architecture minimizes Electromagnetic interference (EMI) emissions while providing high efficiency at high switching frequencies.
