If the unregulated input carries 1 V p-p of 120 Hz ripple, the output sees roughly 1 mV p-p — enough headroom for a 12-bit ADC reference rail or a low-noise op-amp supply without an additional LC filter stage. ## Protection and temperature envelope Built-in over-temperature and short-circuit protection let the part survive a momentary output short or a thermal overload without external clamp diodes. No official second-source alternate is listed, but the LM337 family is widely cross-referenced — confirm pin-compatibility with the specific BOM position before substituting.","metaTitle":"LM337LMX/NOPB Negative Adjustable Regulator, 100 mA, 8-SOIC","metaDescription":"Texas Instruments LM337LMX/NOPB negative adjustable voltage regulator, 100 mA output, -1.2 V to -37 V range, 60 dB PSRR at 120 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"60dB (120Hz)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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":"8-SOIC","Voltage - Output (Min/Fixed)":"-1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/56f5cd2381b15dfce00eeb97931fe2ab.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM337LMX%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM337LMX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM337LMX-NOPB when reusing this data.
