It covers a 1.2 V to 32 V output range from a 38 V max input. Protection features — over-current, over-temperature, short-circuit — are built in, so a momentary output short won't kill the part. ## Output current, PSRR, and quiescent current — the numbers that matter At 100 mA output, the LM317LILP is a low-current rail builder. The quiescent current is 2.5 mA typ — that's the overhead the regulator burns just to regulate, so at a 10 mA load the efficiency is already below 80%. For battery-powered designs, that Iq matters. PSRR runs 80 dB to 65 dB at 120 Hz, which is typical for a three-terminal adjustable regulator. The 80 dB figure applies at lower output voltages; as the output voltage rises toward 32 V, the PSRR drops to 65 dB. That's enough to clean up 120 Hz ripple from a rectified mains supply but not for a switching pre-regulator at 100 kHz — the PSRR at higher frequencies is not specified here. ## Active production — no end-of-life clock ticking The TO-92-3 package and through-hole mounting mean it's a straightforward hand-assembly or wave-solder part — no reflow profile to qualify. Sourcing is through our distributor network against an RFQ.","metaTitle":"LM317LILP – TI Adjustable Positive Regulator, 100 mA, TO-92","metaDescription":"Texas Instruments LM317LILP adjustable positive voltage regulator, 100 mA output, 1.2 V to 32 V range, TO-92-3 package, active lifecycle, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"80dB ~ 65dB (120Hz)","Series":"-","Package":"Bulk","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":"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":"TO-92-3","Current - Quiescent (Iq)":"2.5 mA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","priceTiers":[{"qty":1,"price":"$0.99000","currency":"USD"},{"qty":10,"price":"$0.88800","currency":"USD"},{"qty":25,"price":"$0.84280","currency":"USD"},{"qty":100,"price":"$0.69240","currency":"USD"},{"qty":250,"price":"$0.64724","currency":"USD"},{"qty":500,"price":"$0.57198","currency":"USD"},{"qty":1000,"price":"$0.45156","currency":"USD"},{"qty":2500,"price":"$0.42600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6e1b4db1f31e3d4f44355e3bccdda90e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM317LILP/alternatives.json"},"ai":{"faq":[{"question":"What is the output current rating of LM317LILP?","answer":"The LM317LILP is rated for 100 mA continuous output.
