It is a single positive regulator rated for 400 mA continuous output, with a maximum dropout of 1 V at 50 mA load. The 2 mA quiescent current keeps the idle draw low for always-on rails. ## Protection features reduce external component count Built-in protection against over-temperature, reverse polarity, and short circuit means this regulator can survive a miswired supply or a brief output fault without external clamp diodes or crowbar circuits. For a 24 V industrial control board, the 26 V input maximum provides headroom for a nominal 24 V rail with transients. ## SOT-223-4 footprint and thermal considerations Housed in the SOT-223-4 surface-mount package, the part is compatible with standard SOT-223 land patterns.","metaTitle":"LM2937IMP-2.5 LDO Regulator, Fixed 2.5 V, 400 mA, SOT-223-4","metaDescription":"LM2937IMP-2.5 fixed 2.5 V output LDO, 400 mA, 26 V max input, 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":"-","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":"400mA","Base Product Number":"LM2937","Protection Features":"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 @ 50mA","Current - Supply (Max)":"1.25 A","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-223-4","Current - Quiescent (Iq)":"2 mA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fde2ea9d87633116f7579b8ea9d1fc83.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2937IMP-2.5/alternatives.json"},"ai":{"faq":[{"question":"Is LM2937IMP-2.5 obsolete and what is its replacement?","answer":"Yes, the LM2937IMP-2.5 is obsolete.
