The enable pin (Control Features) lets a host processor shut the LDO off entirely, dropping Iq to near zero in standby. Texas Instruments no longer manufactures it, and no last-time-buy window is open. There is no official TI replacement listed on the record, so any substitution requires pin-compatible validation against the existing layout. ## Package and temperature grade — fits industrial and portable gear Housed in a 5-pin SOT-23-5 (SC-74A), this is a surface-mount part with a 0.95 mm pitch — standard for hand-assembly or reflow. Protection features include over-current, over-temperature, and short-circuit, so it handles a momentary output short without letting the magic smoke out.","metaTitle":"LP2980AIM5-1.8/NOPB LDO Regulator, 1.8V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIM5-1.8/NOPB is a 50mA fixed-output LDO with 63dB PSRR at 1kHz, 0.22V max dropout, 95µA Iq.","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); Cut Tape (CT)","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)":"1.8V"}},"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/LP2980AIM5-1.8%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980AIM5-1.8/NOPB obsolete?","answer":"Yes, the product status is listed as Obsolete.
