That is the number that separates it from a standard multi-rail regulator — the 32 µA quiescent means this PMIC can sit on a battery-backed always-on rail without draining the cell during sleep or standby. It is designed for systems where the processor core needs sequenced, low-noise rails and the system spends most of its life in a low-power state. ## 81-DSBGA — the footprint reality The package is an 81-ball DSBGA, 3.6 x 3.6 mm body, with a 0.5 mm ball pitch. That is a fine-pitch BGA — no two-layer board will route this out. Expect a four-layer PCB with microvias or via-in-pad to break out the inner balls. The supplier device package is 81-DSBGA (3.6x3.6). Surface-mount only; no socket exists for field-swap, so this is a rework-station part, not a field-replaceable one.","metaTitle":"TPS659121YFFR PMIC, 32 µA supply, -40°C to 85°C, 81-DSBGA","metaDescription":"Texas Instruments TPS659121YFFR processor PMIC, 1.8V–5.5V input, 32 µA quiescent current, -40°C to 85°C, 81-DSBGA 3.6x3.6 mm.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Processor","Mounting Type":"Surface Mount","Package / Case":"81-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"32µA","Voltage - Supply":"1.8V ~ 5.5V","Base Product Number":"TPS659121","Operating Temperature":"-40°C~85°C","Supplier Device Package":"81-DSBGA (3.6x3.6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3560","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee159614ebcaef65258cb2cba6e95ce1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS659121YFFR/alternatives.json"},"ai":{"faq":[{"question":"What processors does TPS659121YFFR support?","answer":"The application field is listed as Processor. This is a general-purpose processor PMIC — it provides the sequenced, low-noise power rails that an application processor (ARM, x86, DSP) needs. The exact processor compatibility depends on the voltage and current requirements of the specific core and I/O rails; the datasheet details the output rail configuration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS659121YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS659121YFFR when reusing this data.
