That means the input rail must stay above 16 V to keep the output in regulation; budget 16.5 V minimum for margin across temperature and line transients. Output configuration is positive and fixed — no external resistor divider needed, which saves two resistors and a feedback node on the board. ## Protection set and quiescent current On-chip protection covers over current, over temperature, reverse polarity, and short circuit — the regulator survives a hard output short or a reversed input battery without external clamp diodes. Quiescent current is 10 mA typical, with a supply current maximum of 15 mA. That Iq is higher than a modern CMOS LDO, but the LM2940 series was designed for low-dropout bipolar performance; the trade-off is a few milliamps of standing current for 1 A output capability and robust fault tolerance. ## Package and temperature grade — SOT-223 layout Not AEC-Q100 qualified, so not a direct fit for under-hood automotive, but fine for cabin electronics or auxiliary power in a non-critical path.","metaTitle":"LM2940IMP-15/NOPB — 15V 1A Fixed LDO, SOT-223, Active","metaDescription":"Texas Instruments LM2940IMP-15/NOPB: fixed 15V output, 1A LDO, 1V max dropout at 1A, industrial temp -40°C to 85°C, SOT-223-4 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"-","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-261-4, TO-261AA","Product Status":"Active","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)":"15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4000","priceTiers":[{"qty":1,"price":"$2.40000","currency":"USD"},{"qty":10,"price":"$2.15500","currency":"USD"},{"qty":25,"price":"$2.03240","currency":"USD"},{"qty":100,"price":"$1.73170","currency":"USD"},{"qty":250,"price":"$1.62604","currency":"USD"},{"qty":500,"price":"$1.42278","currency":"USD"},{"qty":1000,"price":"$1.17888","currency":"USD"},{"qty":2000,"price":"$1.15050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f1c4256f4019947c4206f2126daf8930.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2940IMP-15%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is the LM2940IMP-15/NOPB obsolete?","answer":"No — the product status is Active.
