Its PSRR of 63 dB at 1 kHz makes it a candidate for powering analog blocks — ADC references, op-amp rails, or sensor front-ends — where a switching regulator would inject ripple into the signal path. ## Dropout and quiescent current — the headroom trade-off Maximum dropout is 0.22 V at the full 50 mA load, so a 5.0 V rail needs an input above about 5.22 V to stay in regulation. Quiescent current is 95 µA typical, rising to 1.2 mA max under all conditions — low enough for always-on domains in battery-powered gear, though not the ultra-low-Iq tier for coin-cell designs. For a production BOM, the realistic path is sourcing remaining factory inventory or verified surplus through independent distribution. ## 5-µSMD — board area vs. assembly care The 5-µSMD package measures 0.93x1.11 mm — roughly the size of a grain of pepper. It saves real estate on a dense mixed-signal board, but the fine-pitch bumps demand a controlled reflow profile and post-assembly X-ray inspection. The Enable pin (active-high) lets a system supervisor gate the output during power sequencing or sleep modes.","metaTitle":"LP2980IBP-5.0/NOPB LDO Regulator, 5V Fixed, 50mA, 5-µSMD","metaDescription":"Texas Instruments LP2980IBP-5.0/NOPB LDO regulator, 5V fixed output, 50mA, PSRR 63dB at 1kHz, 5-µSMD package.","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":"-","Packaging":"Tape & Reel (TR)","Output Type":"Fixed","Part Status":"Obsolete","Mounting Type":"Surface Mount","Package / Case":"5-VFBGA","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)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IBP-5.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980IBP-5.0/NOPB obsolete?","answer":"Yes, Texas Instruments lists the LP2980IBP-5.0/NOPB as Obsolete. No official successor part number has been published for this exact fixed-5.0 V, 5-µSMD variant. For a replacement, consider a parametric search on the LP2980 base product number — the LP2980 family includes other fixed-voltage and adjustable options in larger packages (e.g., SOT-23, WSON) that may still be active."},{"question":"What is the difference between LP2980IBP-5.0 and LP2980IBP-5.0/NOPB?","answer":"The /NOPB suffix indicates lead-free / RoHS-compliant construction. The LP2980IBP-5.0 (without /NOPB) is the tin-lead version. Electrically they are identical — same 5.0 V fixed output, same 50 mA rating, same 5-µSMD package.
