The 0.22 V maximum dropout at 50 mA means the input can sit as low as 3.52 V and still hold regulation, which matters in battery-powered gear where the cell voltage sags under load. With 63 dB of ripple rejection at 1 kHz, this part attenuates a 100 mVpp supply ripple down to roughly 70 µVpp at the output. That is enough to keep switching-regulator hash off a 3.3 V analog rail without a post-filter LC stage. The 5-µSMD (0.93x1.11 mm) package requires a hot-air rework station for removal and replacement — not a field-swap part for a technician's kit. Plan for a controlled reflow profile if you need to replace it on a board.","metaTitle":"LP2980IBPX-3.3/NOPB LDO Regulator, 3.3V Fixed Output, 50mA","metaDescription":"Texas Instruments LP2980IBPX-3.3/NOPB is a 50mA LDO regulator with fixed 3.3V output, 0.22V dropout, 63dB PSRR at 1kHz, and -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":"5-VFBGA","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":"5-µSMD (0.93x1.11)","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eabcfdbdb17bcf38ee7ef2c6d535c154.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IBPX-3.3%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2980IBPX-3.3-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/LP2980IBPX-3.3-NOPB when reusing this data.
