It belongs to the Automotive, AEC-Q100 qualified series, meaning it has passed the stress tests required for under-hood and chassis-domain electronics — temperature cycling, high-temperature operating life, and ESD robustness. An integrated synchronous rectifier eliminates the external Schottky diode that older nonsynchronous bucks require — one fewer BOM line, one fewer soldered joint, and better efficiency at light loads. ## Package and thermal design Package is 16-TSSOP-EP. Operating temperature range is -40°C to 125°C. Mounting type is surface mount. ## Sourcing and lifecycle ROHS3 compliant, so it passes the EU RoHS exemption list for automotive.","metaTitle":"MAX16903RAUE50/V+ Buck Regulator, 5V Fixed Output, 1A","metaDescription":"Maxim MAX16903RAUE50/V+ automotive step-down regulator: 3.5V-28V input, 5V fixed output at 1A, 2.1MHz switching, -40°C to 125°C.
