The 2.5 mA quiescent current is typical for a three-terminal adjustable regulator at this current level. ## PSRR and protection — why it still matters for legacy boards Power-supply rejection ratio runs 80 dB at 120 Hz, dropping to 65 dB at the same frequency — that is the ripple rejection a designer gets on a full-wave rectified rail. Built-in over-current, over-temperature, and short-circuit protection mean the regulator handles fault conditions without external clamp diodes or crowbar circuits — a practical advantage in a repair or retrofit scenario where board space is already fixed. ## Package and temperature grade — TO-92-3 in industrial environments Housed in a TO-226-3 / TO-92-3 through-hole package, the LM317LILPE3 is a three-lead device with a plastic body.","metaTitle":"LM317LILPE3 Adjustable Linear Regulator, 100 mA, TO-92-3","metaDescription":"LM317LILPE3 adjustable positive voltage regulator, 100 mA output, 38 V input max, PSRR 80dB ~ 65dB at 120Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e1b4db1f31e3d4f44355e3bccdda90e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM317LILPE3/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for LM317LILPE3?","answer":"No official successor or cross-reference is listed for the LM317LILPE3. A common field alternative is the LM317LZ, which is the same LM317L low-current family in a TO-92 package, but verify pin compatibility and output current rating against your specific load. The LM317LILPE3 is pin-compatible with other TO-92 LM317L variants, but without a manufacturer-issued cross-reference, any substitution should be validated against the original design's thermal and load requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM317LILPE3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM317LILPE3 when reusing this data.
