PSRR is 63 dB at 1 kHz, which knocks down switching-regulator ripple by a factor of roughly 1400. This part is officially marked Obsolete. For a repair or a legacy BOM line, the only path is independent distribution, sourced per RFQ. There is no pin-compatible direct replacement from TI with the same fixed 4.7 V output in this package; the LP2980 family has other fixed voltages (3.3 V, 5.0 V) that share the same pinout, but a 4.7 V rail is uncommon enough that a board spin or a different regulator family is the realistic move for new production.","metaTitle":"LP2980IM5X-4.7/NOPB LDO Regulator, 4.7V Fixed, 50mA","metaDescription":"Texas Instruments LP2980IM5X-4.7/NOPB is a fixed 4.7V LDO rated for 50mA output with 0.22V max dropout. 63dB PSRR at 1kHz. -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"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)":"4.7V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IM5X-4.7%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Can I replace LP2980IM5X-4.7/NOPB with LP2980IM5X-3.3?","answer":"The pinout and package are identical — both are SOT-23-5 with the same Enable and protection features. The only difference is the fixed output voltage: 4.7 V versus 3.3 V. If your load actually needs 4.7 V, swapping to the 3.3 V variant will drop the rail below spec. For a 3.3 V design the 3.3 V variant is a direct drop-in replacement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2980IM5X-4.7-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/LP2980IM5X-4.7-NOPB when reusing this data.
