It is qualified to AEC-Q100. ## Key ratings and what they mean for the BOM 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. ## Package and mounting The part comes in a 16-TQFN (5x5 mm) with an exposed pad — that's a QFN, not a QFP. The exposed pad needs a thermal via array under it to pull heat into the board plane; without it the 400 mA at high input voltage will push the die temperature past the 125°C limit. 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. ## Lifecycle and sourcing posture The part is safe to qualify for a new automotive program without an immediate LTB risk. No direct second-source alternate is listed in the official record.","metaTitle":"MAX5087BATE/V+ Automotive LDO Regulator, 400mA, 45V Input","metaDescription":"MAX5087BATE/V+ automotive LDO: 400mA output, 45V max input, PSRR 70dB at 100Hz, AEC-Q100, -40°C to 125°C.

The MAX5087 family includes fixed-voltage variants in the same 16-TQFN package that share the pinout — if your output voltage is fixed (e.g. 5 V), a fixed-output sibling may be a drop-in substitute without the feedback resistor network."},{"question":"What does the 70 dB PSRR at 100 Hz mean for my design?","answer":"The 70 dB PSRR at 100 Hz means this LDO attenuates 100/120 Hz ripple from a rectified alternator or AC-DC front end by a factor of about 3,160 — so a 1 V p-p ripple on the input becomes roughly 0.3 mV p-p on the output. That is the spec that makes this part suitable for powering sensitive analog loads (sensor signal chains, ADC references) in a vehicle where the battery line carries alternator whine."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5087BATE-V","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5087BATE-V when reusing this data.
