The MAX5087BATE/V+ is a single-output, positive-adjustable linear voltage regulator rated for 400 mA output with a 45 V maximum input. It is qualified to AEC-Q100.
Protection features include over-current, over-temperature, and short-circuit shutdown — the three faults most common on an automotive power rail. The Enable and Reset control features let a system supervisor sequence the rail on/off and monitor its output status, which simplifies compliance with ASIL-oriented power-up diagnostics.
The part comes in a 16-TQFN (5x5 mm) with an exposed pad — that's a QFN, not a QFP. For rework: the 5x5 mm body is manageable with hot air if you preheat the board from the bottom. The pad is symmetric, so mark pin 1 orientation before lifting the old part — the TQFN has no visible notch on a rework scope if the solder mask is dark. Lift the part, not the pad.
The part is safe to qualify for a new automotive program without an immediate LTB risk.
