The bucks cover 0.7 V to 3.36 V; the LDOs cover 0.8 V to 3.3 V — enough range to power a modern SoC core, memory I/O, and analog front-end from one IC. Switching at 2 MHz lets the output filter components shrink — a 1 µH inductor and 10 µF ceramic cap per buck channel fit the bill for most automotive processor rails, saving board area in an ECU that already has tight real estate. ## AEC-Q100 Grade 1 — -40°C to 125°C ambient, 2.8 V to 5.5 V input Qualified to AEC-Q100 Grade 1, the LP87334ARHDRQ1 operates from -40°C to 125°C ambient — the full under-hood temperature band. The 2.8 V to 5.5 V input range covers a 12 V battery dipped to 4.5 V during cold crank and survives a 40 V load-dump transient when the alternator field decays, as long as the upstream TVS clamps the bus within the abs-max rating. The integrated power sequencer manages the four rail start-up order without an external supervisor — one less IC to qualify and one less trace to route on the board. The sequencer timing is programmable, so the core rail can ramp before the I/O rail, matching the SoC's power-up sequence. ## Wettable flank QFN — AOI-friendly and reworkable The 28-VFQFN package uses wettable flanks — the side of each pad is plated so solder wicks up the edge, creating a visible fillet that automated optical inspection (AOI) can verify. For the rework bench, that means you can see the joint quality after hot-air removal and replacement without X-ray. The 5 mm × 5 mm footprint (28-VQFN) with exposed thermal pad pulls heat into the board's copper plane. The pad's solder paste coverage should match the recommended stencil aperture in the datasheet — too much paste and the part floats; too little and the thermal resistance climbs. ## Active production — no LTB, no obsolescence risk The part is current for both new designs and production replenishment. Sourced through authorized and independent distribution channels; availability and current pricing confirmed at RFQ against your BOM quantity.","metaTitle":"Texas Instruments LP87334ARHDRQ1 PMIC","metaDescription":"Texas Instruments LP87334ARHDRQ1 automotive PMIC: dual 3A buck converters + dual 300mA LDOs, 2.8-5.5V input, AEC-Q100, 28-VFQFN.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Down (Buck) (2), Linear (LDO) (2)","w/Sequencer":"Yes","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"28-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.8V ~ 5.5V","Number of Outputs":"4","Frequency - Switching":"2MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"28-VQFN (5x5)","Voltage/Current - Output 1":"Programmable, Programmable, Programmable, 0.7V ~ 3.36V, 3A","Voltage/Current - Output 2":"Programmable, Programmable, Programmable, 0.7V ~ 3.36V, 3A","Voltage/Current - Output 3":"Programmable, Programmable, Programmable, 0.8V ~ 3.3V, 300mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.82000","currency":"USD"},{"qty":10,"price":"$4.32900","currency":"USD"},{"qty":25,"price":"$4.09280","currency":"USD"},{"qty":100,"price":"$3.54710","currency":"USD"},{"qty":250,"price":"$3.36516","currency":"USD"},{"qty":500,"price":"$3.01956","currency":"USD"},{"qty":1000,"price":"$2.54661","currency":"USD"},{"qty":3000,"price":"$2.41928","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4c2c420c440da112c26ad721c3e83c96.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the LP87334ARHDRQ1 come in?","answer":"It is supplied in a 28-VFQFN with wettable flank (5 mm × 5 mm, 0.5 mm pitch).
