The single regulator integrates over-temperature shutdown and output short-circuit protection — no external crowbar or thermal cutoff needed for basic fault coverage.","metaTitle":"LM337LZ/LFT3 Adjustable Negative Regulator, 100 mA, TO-92-3","metaDescription":"Texas Instruments LM337LZ/LFT3 adjustable negative linear regulator, 100 mA output, -1.2 V to -37 V, TO-92-3 package, 60 dB PSRR at 120 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"60dB (120Hz)","Series":"-","Package":"Cut Tape (CT); Tape & Box (TB)","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LM337","Protection Features":"Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Negative","Operating Temperature":"-25°C~125°C","Voltage - Input (Max)":"-40V","Voltage Dropout (Max)":"-","Voltage - Output (Max)":"-37V","Supplier Device Package":"TO-92-3","Voltage - Output (Min/Fixed)":"-1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.86600","currency":"USD"},{"qty":25,"price":"$0.82200","currency":"USD"},{"qty":100,"price":"$0.67530","currency":"USD"},{"qty":250,"price":"$0.63128","currency":"USD"},{"qty":500,"price":"$0.55788","currency":"USD"},{"qty":1000,"price":"$0.44043","currency":"USD"},{"qty":2000,"price":"$0.41550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/56f5cd2381b15dfce00eeb97931fe2ab.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM337LZ%2FLFT3/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM337LZ/LFT3 in the same family?","answer":"The TO-92-3 package of the LM337LZ is footprint-constrained — the LM337T is not drop-in compatible due to the different package and pin spacing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM337LZ-LFT3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM337LZ-LFT3 when reusing this data.
