The output voltage is adjustable from a minimum of 1.25 V up to 16 V, set by an external resistor divider — the 1.25 V reference is the feedback threshold, not a fixed output. ## 8-DFN exposed pad — thermal and layout checklist The 8-WFDFN package with exposed pad (3 mm × 2 mm body) requires a thermal land on the PCB to conduct heat from the die to the board — without a proper via array under the pad, the junction temperature rises above the 85°C ambient limit at full load.","metaTitle":"LT3470AEDDB#TRPBF Buck Regulator, 250mA, 40V Input, 8-DFN","metaDescription":"Active-production LT3470AEDDB#TRPBF step-down regulator from Analog Devices. 250mA output, 40V max input, adjustable 1.25-16V. 8-WFDFN package.
