Procurement must go through the independent surplus and broker channel. Stock that surfaces after an official EOL announcement should be date-code verified — the PCN bulletin for the LM2937 family is the reference for authenticating production lots. ## 26 V input ceiling — plan for the pre-regulator Maximum input voltage is 26 V. The 2 mA quiescent current (20 mA max supply current) keeps the overhead low for always-on rails. ## DDPAK footprint and thermal management","metaTitle":"Texas Instruments LM2937ESX-15 15V Fixed LDO, 500mA, TO-263","metaDescription":"Texas Instruments LM2937ESX-15 fixed 15V LDO regulator, 500mA output, TO-263-3 DDPAK.","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-263-4, D²Pak (3 Leads + Tab), TO-263AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"500mA","Base Product Number":"LM2937","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"1V @ 50mA","Current - Supply (Max)":"20 mA","Voltage - Output (Max)":"-","Supplier Device Package":"DDPAK/TO-263-3","Current - Quiescent (Iq)":"2 mA","Voltage - Output (Min/Fixed)":"15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fde2ea9d87633116f7579b8ea9d1fc83.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2937ESX-15/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2937ESX-15","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2937ESX-15 when reusing this data.
