It accepts a 3.5V to 36V input and delivers up to 3A with a programmable output voltage fixed at 1V or 3.3V.
The 3.5V minimum input covers cold-crank conditions on a 12V automotive bus, while the 36V maximum handles load-dump transients without external clamping. The 3A continuous output is sized for powering sensor clusters, CAN transceiver rails, or a small MCU core supply.
ROHS3 compliance is already in place, so no additional exemption paperwork is needed for EU-market builds.
Yes, the MAX20003ATPB/V+T is part of the Automotive, AEC-Q100 series, meaning it is qualified for automotive-grade reliability and temperature requirements.
