AEC-Q100 Grade 1 (125°C ambient) qualifies the part for under-hood or engine-bay electronics where the junction temperature can exceed 105°C on a hot day. ## Package, footprint, and rework notes The part is supplied in a 5-lead SOT-753 package (SC-74A), also designated as SOT-25. The 0.95 mm pitch and 2.9 mm body length fit a standard small-signal LDO footprint; the exposed die attach pad on the bottom side should be soldered to a PCB copper land for thermal conduction. The Enable pin (active-high, internal pull-down) lets the system power-gate the LDO — pulling it low drops the quiescent current from 60 µA to near zero, useful for battery-backed modules that sleep between ignition cycles. Protection features include over-current, over-temperature, and short-circuit shutdown — the LDO folds back current and latches off until the fault clears, preventing thermal runaway in a harness short. ROHS3 compliant — no exemptions for lead or phthalates, so it ships into EU and UKCA markets without restriction.","metaTitle":"AP7343DQ-28W5-7 LDO, 2.8V 300mA, AEC-Q100, SOT-25","metaDescription":"AP7343DQ-28W5-7 LDO regulator, 2.8V fixed output, 300mA, 75dB PSRR at 1kHz, AEC-Q100 automotive grade, -40°C to 125°C, SOT-25 package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"PSRR":"75dB (1kHz)","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"300mA","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Input (Max)":"5.25V","Voltage Dropout (Max)":"0.32V @ 300mA","Supplier Device Package":"SOT-25","Current - Quiescent (Iq)":"60 µA","Voltage - Output (Min/Fixed)":"2.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.42000","currency":"USD"},{"qty":10,"price":"$0.35600","currency":"USD"},{"qty":25,"price":"$0.33240","currency":"USD"},{"qty":100,"price":"$0.26580","currency":"USD"},{"qty":250,"price":"$0.24684","currency":"USD"},{"qty":500,"price":"$0.20886","currency":"USD"},{"qty":1000,"price":"$0.16140","currency":"USD"},{"qty":3000,"price":"$0.14716","currency":"USD"},{"qty":6000,"price":"$0.13766","currency":"USD"},{"qty":15000,"price":"$0.12817","currency":"USD"},{"qty":30000,"price":"$0.12152","currency":"USD"},{"qty":75000,"price":"$0.11867","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/68d70890c25f0e0fe1b44d4c67830b93.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to AP7343DQ-28W5-7?","answer":"The AP7343Q-33W5-7 is the closest peer in the same AP7343 family — same AEC-Q100 grade, same 300 mA output, same 75 dB PSRR, same SOT-25 package — but its output is fixed at 3.3 V instead of 2.8 V.
