For high-volume pick-and-place lines, verify the feeder setup accepts bulk tubes or request the tape-and-reel variant if one exists. The 40-LLP-EP (5x5) supplier device package is TI's naming for the same 40-lead WFQFN with exposed pad — the PCB land pattern is identical regardless of the delivery medium.","metaTitle":"LP3972SQX-A514/NOPB Power Sequencer, 60 µA, 40-WFQFN","metaDescription":"LP3972SQX-A514/NOPB processor power sequencer, 60 µA supply, 2.7-5.5 V input, 40-WFQFN, -40 to 85°C.

In a 1000 mAh Li-ion system, the sequencer alone consumes about 1.4% of capacity per year if the system is always powered."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP3972SQX-A514-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP3972SQX-A514-NOPB when reusing this data.
