It is a surface-mount variant of the classic LM317 family in an 8-SOIC package, suited for generating a clean local rail from a higher unregulated supply up to 38 V input. ## PSRR and protection in harsh environments PSRR is specified at 80 dB typical at 120 Hz, dropping to 65 dB — this matters for attenuating rectified mains ripple in audio, instrumentation, or sensor bias supplies. The regulator includes over-current, over-temperature, and short-circuit protection, reducing the need for external clamp or foldback circuits.","metaTitle":"LM317LID adjustable voltage regulator, 100 mA, 8-SOIC","metaDescription":"LM317LID adjustable positive voltage regulator, 100 mA output, 1.2 V to 32 V, PSRR 80 dB at 120 Hz, -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":"-","Packaging":"Tube","Output Type":"Adjustable","Part Status":"Last Time Buy","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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)":"38V","Voltage Dropout (Max)":"-","Voltage - Output (Max)":"32V","Supplier Device Package":"8-SOIC","Current - Quiescent (Iq)":"2.5 mA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e1b4db1f31e3d4f44355e3bccdda90e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM317LID/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between LM317LID and LM317L?","answer":"The LM317LID is the surface-mount 8-SOIC version of the LM317L, which is typically offered in a through-hole TO-92 or TO-220 package.
