Below that the output starts to fold. The 26 V absolute-maximum input gives you headroom for unregulated supplies up to 24 V nominal. ## Lifecycle — obsolete, but still sourced TI has marked this part obsolete (product status: Obsolete). Every unit we quote is sourced from verified distributor inventory, date-code checked, and shipped against your RFQ. Housed in a SOT-223-4 (TO-261-4 equivalent) surface-mount package.","metaTitle":"LM2940IMP-8.0/NOPB 8V 1A LDO Regulator","metaDescription":"Texas Instruments LM2940IMP-8.0/NOPB fixed 8V output LDO, 1A current, 66dB PSRR at 120Hz, SOT-223-4.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"66dB (120Hz)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-261-4, TO-261AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"1A","Base Product Number":"LM2940","Protection Features":"Over Current, Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~85°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"1V @ 1A","Current - Supply (Max)":"15 mA","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-223-4","Current - Quiescent (Iq)":"10 mA","Voltage - Output (Min/Fixed)":"8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f38d6c1a461ac905342e1b9990545fb3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2940IMP-8.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM2940IMP-8.0/NOPB?","answer":"This obsolete part is not available through the factory channel."},{"question":"Is LM2940IMP-8.0/NOPB obsolete and can I still buy it?","answer":"Yes, it is officially obsolete per the manufacturer.
