Maximum dropout is 0.22 V at 50 mA. ## Industrial temperature grade and protection set On-chip protection includes over-current, over-temperature, and short-circuit shutdown — no external watchdog or crowbar needed for fault survival. The enable pin gates the output rail during sleep. Available stock is limited to surplus and excess inventory held by independent distributors. No official replacement or cross-reference is recorded in the TI lifecycle notice for this specific fixed-voltage variant. Buyers should evaluate the LP2980 family for a pin-compatible voltage option or consider a newer-generation LDO with equivalent SOT-23-5 footprint. ## Package and footprint — SOT-23-5 Supplied in a 5-pin SOT-23-5 surface-mount package.","metaTitle":"LP2980AIM5-2.8/NOPB LDO Regulator, 2.8V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIM5-2.8/NOPB 50mA LDO, fixed 2.8V output, 63dB PSRR at 1kHz, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"63dB (1kHz)","Series":"-","Package":"Tape & Reel (TR)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"50mA","Base Product Number":"LP2980","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"16V","Voltage Dropout (Max)":"0.22V @ 50mA","Current - Supply (Max)":"1.2 mA","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"2.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-2.8%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980AIM5-2.8/NOPB obsolete?","answer":"Yes, Texas Instruments lists this part as Obsolete. No factory orders are being accepted."},{"question":"What is the replacement for LP2980AIM5-2.8/NOPB?","answer":"No official replacement has been published by Texas Instruments for this specific fixed 2.8 V output variant. The LP2980 family shares the same SOT-23-5 footprint and pinout across output voltages, so a different fixed-voltage LP2980 variant (e.g. 3.3 V or adjustable) may be a drop-in substitute if the output voltage can be changed. For a newer-generation LDO, evaluate parts with equivalent 50 mA rating and SOT-23-5 package."},{"question":"What is the difference between LP2980AIM5-2.8/NOPB and LP2980AIM5-3.3?","answer":"The two parts are identical in package (SOT-23-5), pinout, 50 mA output current, dropout voltage, and protection features. The only difference is the fixed output voltage: 2.8 V for this part versus 3.3 V for the LP2980AIM5-3.3 variant. If your load can tolerate the voltage change, the 3.3 V version is a direct footprint and pin-compatible alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2980AIM5-2.8-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/LP2980AIM5-2.8-NOPB when reusing this data.
