It operates from a 4.5V to 18V supply, draws 2.1mA quiescent current, and is rated over -40°C to 105°C — the industrial/automotive cabin temperature grade, not full under-hood 125°C. Packaged in a 16-WQFN Exposed Pad (16-TQFN 4x4mm), it is surface-mount and AEC-Q100 qualified, making it suitable for ECU power management, sensor supply, and always-on modules where the thermal profile stays below 105°C ambient. ## AEC-Q100 qualification — what it means for your BOM The MAX16946GTE/V+ carries AEC-Q100 qualification, which means it has passed the automotive stress tests for temperature cycling, ESD, latch-up, and extended life. This is the baseline for any tier-one ECU program — without it, the part doesn't get into the PPAP package. The -40°C to 105°C operating range covers cabin and chassis-mount locations but not engine-bay or exhaust-adjacent spots where 125°C or 150°C grades are required. If your thermal analysis shows junction temperatures exceeding 105°C, you need a different grade. ## Supply voltage and current — sizing the rail The 4.5V to 18V input range covers automotive battery voltage from cold-crank (down to ~4.5V) through load-dump transients up to 18V. The 2.1mA supply current is the quiescent draw — relevant for always-on modules where standby power is budgeted. ## Package and mounting — board-level fit The 16-WQFN Exposed Pad with supplier device package 16-TQFN (4x4mm) is a standard QFN footprint. The exposed pad must be soldered to a thermal via array on the PCB ground plane to dissipate heat — without that, the junction temperature rises quickly under load. Surface-mount only; no through-hole variant exists. The part ships in Tube, not tape-and-reel, so plan for pick-and-place feeder changeover if your line is set up for reels. ## Lifecycle and sourcing reality ROHS3 compliant. No LTB risk, no forced redesign.","metaTitle":"MAX16946GTE/V+ Automotive LDO/Switch Regulator, AEC-Q100","metaDescription":"MAX16946GTE/V+ adjustable LDO/switch regulator from Maxim Integrated, AEC-Q100 qualified, 4.5V–18V input, 2.1mA supply, -40°C to 105°C, 16-TQFN.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, R²Coupler™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"Automotive, AEC-Q100, R²Coupler™","Package":"Tube","Applications":"Automotive Systems, Remote Power","Mounting Type":"Surface Mount","Package / Case":"16-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"2.1mA","Voltage - Supply":"4.5V ~ 18V","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"16-TQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.01000","currency":"USD"},{"qty":10,"price":"$5.42900","currency":"USD"},{"qty":25,"price":"$5.17640","currency":"USD"},{"qty":100,"price":"$4.49450","currency":"USD"},{"qty":250,"price":"$4.29248","currency":"USD"},{"qty":500,"price":"$3.91376","currency":"USD"},{"qty":1000,"price":"$3.40875","currency":"USD"},{"qty":2500,"price":"$3.28250","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX16946-MAX16947.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX16946GTE/V+ AEC-Q100 qualified?","answer":"Yes, the MAX16946GTE/V+ is AEC-Q100 qualified as part of the Automotive, AEC-Q100, R²Coupler™ series.
