It is designed for applications where a clean, regulated 5V rail is needed from a higher input voltage up to 16V. The low dropout of 0.22V max at 50 mA means the input can sit as low as 5.22V and still maintain regulation — useful in battery-powered or post-switcher rails where headroom is tight. ## 63 dB PSRR at 1 kHz — ripple rejection in noisy environments With a PSRR of 63 dB at 1 kHz, this LDO attenuates input ripple by a factor of roughly 1400× at that frequency. For a 100 mVpp ripple on the input, the output sees under 100 µVpp — clean enough to bias a sensitive analog front-end or a reference buffer. The quiescent current is 95 µA typical, so the ripple rejection comes without a heavy idle-current penalty. ## Wide temperature range and protection set On-chip protection includes over-current, over-temperature, and short-circuit — the regulator survives a sustained output short without damage. The enable pin allows external on/off control, reducing quiescent draw to near zero when the rail is not needed. ## NRND — plan a replacement now The part is still available through independent distribution for existing BOM lines, but new designs should select a current-production alternative. The SOT-23-5 footprint is common — many 50 mA LDOs in this package are drop-in candidates, but pinout and enable polarity must be verified against the existing layout.","metaTitle":"LP2980AIM5-5.0 50mA Fixed 5V LDO, NRND, SOT-23-5","metaDescription":"LP2980AIM5-5.0 from Texas Instruments: 50mA fixed 5V LDO, 0.22V dropout at 50mA, PSRR 63dB at 1kHz, -40°C to 125°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"63dB (1kHz)","Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Output Type":"Fixed","Part Status":"Obsolete","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","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)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-5.0/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980AIM5-5.0 obsolete?","answer":"It is not fully discontinued, but it is not recommended for new production builds.
