It is designed for powering low-current analog or digital rails where a clean, regulated 3.0 V supply is needed — think sensor bias, reference buffers, or MCU I/O supply in mixed-signal designs. Key parametrics include a PSRR of 63 dB at 1 kHz, a maximum dropout of 0.22 V at full load, and a quiescent current of 95 µA. The enable pin allows external on/off control, and built-in protection covers over-current, over-temperature, and short-circuit events. ## NRND — plan a last-time buy or second source Existing production BOMs can still be filled through independent distribution, but new designs should select a current-production LDO with the same 3.0 V fixed output and SOT-23-5 footprint. The 0.22 V dropout at 50 mA means the input rail must stay above 3.22 V to maintain regulation — a 3.3 V rail with 100 mV ripple still leaves 20 mV headroom. Below that, the output tracks the input minus dropout, and PSRR collapses. For battery-powered designs, the 95 µA quiescent current is the standby floor; the enable pin can pull that to near zero when the load is off. PSRR of 63 dB at 1 kHz attenuates a 100 mVpp ripple on the input to about 70 µVpp on the output — adequate for 10-bit ADC references but marginal for 16-bit precision without additional post-filtering.","metaTitle":"LP2980AIM5-3.0 LDO Regulator, 3.0 V Fixed, 50 mA, NRND","metaDescription":"LP2980AIM5-3.0 LDO voltage regulator, fixed 3.0 V output, 50 mA, PSRR 63 dB at 1 kHz, 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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Not For New Designs","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)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-3.0/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980AIM5-3.0 obsolete?","answer":"Existing BOMs can still be sourced through independent distribution against an RFQ."},{"question":"What is the replacement for LP2980AIM5-3.0?","answer":"For new designs, evaluate a current-production 3.0 V fixed LDO in SOT-23-5 such as the MIC5205-3.0YM5 or MCP1700-3002E/TO — confirm pin compatibility and dropout specs against your load current."},{"question":"LP2980AIM5-3.0 vs LP2980IM5-3.0 — what is the difference?","answer":"The 'A' suffix in LP2980AIM5-3.0 typically indicates an enhanced or improved version — often tighter output tolerance or wider temperature range.
