Output voltage is set by two external resistors from 1.2 V to 37 V, with a maximum input of 40 V. The 8-SOIC surface-mount package suits compact board layouts where the through-hole LM317T cannot fit. ## PSRR and noise rejection at 120 Hz Ripple rejection is specified at 80 dB to 65 dB at 120 Hz, which is the fundamental frequency of full-wave rectified 60 Hz mains. This means the regulator attenuates input ripple by a factor of 10,000 to 1,800 — sufficient for clean analog supply rails in instrumentation or audio circuits where the downstream PSRR of op-amps is limited. ## Industrial temperature range and protection Built-in protection includes over-current, over-temperature, and short-circuit shutdown — no external clamp diodes needed for output short to ground. The NOPB suffix indicates a lead-free (NiPdAu) finish, RoHS-compliant, and compatible with standard Pb-free reflow profiles.","metaTitle":"LM317LM/NOPB Adjustable Linear Regulator, 100 mA, 8-SOIC","metaDescription":"Texas Instruments LM317LM/NOPB adjustable positive voltage regulator, 100 mA output, 1.2V to 37V range, PSRR 80dB~65dB at 120Hz, -40°C to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"80dB ~ 65dB (120Hz)","Series":"-","Package":"Tube","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":"LM317","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"40V","Voltage Dropout (Max)":"-","Voltage - Output (Max)":"37V","Supplier Device Package":"8-SOIC","Current - Quiescent (Iq)":"5 mA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/89877edfb652138bbc6081139c1ee52e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM317LM%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM317LM-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/LM317LM-NOPB when reusing this data.
