The 2.9 V fixed output and 63 dB PSRR at 1 kHz suit noise-sensitive loads. ## Dropout and quiescent current — sizing the headroom budget Maximum dropout is 0.22 V at the full 50 mA load. For a 2.9 V output, the input must stay above 3.12 V worst-case — a 3.3 V rail with 5 % tolerance (3.135 V min) barely clears it. In battery applications, the dropout figure sets the end-of-discharge voltage: a Li-ion cell at 3.0 V is too low; a 3.6 V or 5 V rail provides comfortable margin. No official successor or pin-compatible second source is recorded in the lifecycle data — each replacement candidate must be validated for output voltage, dropout, and enable logic. Built-in protection includes over-current, over-temperature, and short-circuit shutdown. The Enable control feature allows the regulator to be shut down by a logic signal, reducing quiescent current to near zero when the load is idle — useful for power-gated sensor nodes or intermittent-duty RF transceivers.","metaTitle":"LP2980AIM5X-2.9/NOPB LDO Regulator, 2.9V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIM5X-2.9/NOPB is an obsolete 50mA LDO with fixed 2.9V output, 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":"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)":"2.9V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5X-2.9%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What package does LP2980AIM5X-2.9/NOPB use?","answer":"The device is supplied in an SC-74A / SOT-753 surface-mount package, with the supplier device package listed as SOT-23-5.

The LP2980AIM5-2.9 (without the X suffix) shares the same base product number and output voltage, but its lifecycle and availability must be verified independently — the X suffix typically indicates Tape & Reel packaging, not a functional difference.
