That 1 A rating puts it in the mid-current tier — enough to power a sensor cluster, a small FPGA bank, or a local digital rail on a mixed-signal board, but not a bulk supply. The 2.5 V fixed output is a common core voltage for MCUs and interface logic, so it drops straight into a 2.5 V bus without external resistor dividers. The 2 mA quiescent current is moderate for a 1 A LDO — not the ultra-low-Iq you would pick for a battery-backed always-on rail, but acceptable for an industrial or telecom supply where the regulator is enabled only when the system is running. Enable and Soft Start are both present: Enable lets a power supervisor sequence the rail on and off cleanly, and Soft Start limits the inrush into large capacitive loads, which prevents the input supply from drooping during power-up. Protection features include Over Current and Over Temperature, which means the regulator shuts down before it damages itself or the load under a sustained fault. ## 8-LFCSP footprint — thermal via stitch required The ADM7171ACPZ-2.5-R7 comes in an 8-lead LFCSP-WD measuring 3x3 mm with an exposed pad. That small footprint is attractive for dense layouts, but the exposed pad is the primary heat path — without a via array stitching the pad to an internal ground plane, the junction temperature will exceed the 125°C limit well before 1 A continuous output. The pad also doubles as the electrical ground connection, so the PCB layout must tie it to the ground plane with low thermal resistance.","metaTitle":"ADM7171ACPZ-2.5-R7 LDO Regulator, Fixed 2.5V, 1A, 8-LFCSP","metaDescription":"ADI ADM7171ACPZ-2.5-R7 is a 1A LDO with fixed 2.5V output, 6.5V max input, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad, CSP","lifecycle_stage":"eol_hot","Control Features":"Enable, Soft Start","Current - Output":"1A","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"6.5V","Current - Supply (Max)":"6.3 mA","Supplier Device Package":"8-LFCSP-WD (3x3)","Current - Quiescent (Iq)":"2 mA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.34","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.55000","currency":"USD"},{"qty":10,"price":"$4.08700","currency":"USD"},{"qty":25,"price":"$3.86360","currency":"USD"},{"qty":100,"price":"$3.34850","currency":"USD"},{"qty":250,"price":"$3.17680","currency":"USD"},{"qty":500,"price":"$2.85056","currency":"USD"},{"qty":1500,"price":"$2.43000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7fd23a0baee7945a85dbcad1c7b9c6ee.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADM7171ACPZ-2.5-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADM7171ACPZ-2.5-R7 when reusing this data.
