Any new-design or repair BOM that calls out this exact code will need to source from independent distribution or qualify a substitute part. ## 5 V fixed output with 0.3 V dropout at 100 mA This is a single-output positive fixed LDO delivering 5 V at up to 100 mA. The maximum dropout voltage is 0.3 V at full load, so the input rail must stay above 5.3 V to maintain regulation. Input can go as high as 26 V, making it usable on 12 V or 24 V buses without a pre-regulator. ## PSRR and protection for noise-sensitive rails PSRR is 55 dB at 120 Hz, which provides decent mains-ripple rejection for analog supply rails in industrial or automotive environments. On-chip protection covers over-temperature, reverse polarity, and short circuit – useful when the regulator sees a faulted input or output. ## 6-VFBGA package – layout realities The part comes in a 6-VFBGA (6-uSMD) package with surface-mount termination. The 0.50 mm ball pitch and small footprint require careful PCB layout – the thermal dissipation is limited by the board copper, not the package itself. Quiescent current is 1 mA typical; maximum supply current is 15 mA. ## Temperature grade and operating range Not specified for extended automotive under-hood or military temperature ranges.","metaTitle":"LM2931IBP-5.0/NOPB LDO Regulator, 5V Fixed, 100mA, 6-uSMD","metaDescription":"Texas Instruments LM2931IBP-5.0/NOPB positive fixed LDO, 5V output, 100mA, 55dB PSRR at 120Hz, dropout 0.3V max, 6-VFBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"55dB (120Hz)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-VFBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LM2931","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~85°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"0.3V @ 100mA","Current - Supply (Max)":"15 mA","Voltage - Output (Max)":"-","Supplier Device Package":"6-uSMD","Current - Quiescent (Iq)":"1 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bc5f9d253d87c0f5bb975d3751d9071d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2931IBP-5.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM2931IBP-5.0/NOPB obsolete?","answer":"Yes, Texas Instruments lists this part as obsolete.
