Output voltage is set with two external resistors from a 1.25 V reference up to 13.8 V. The TO-252-3 (DPak) package has a metal tab that conducts heat to the board copper — the tab is the output, so the PCB layout ties it to the load return plane. With 75 dB of ripple rejection at 120 Hz, this LDO attenuates full-wave-rectified ripple. That matters when the input comes from a bulk capacitor after a bridge rectifier — the output sees microvolts of ripple instead of millivolts. For an adjustable part, the PSRR holds across the output range because the internal error amplifier runs from the unregulated input. ## Industrial temperature range and protection On-chip protection includes over-current and over-temperature shutdown — the part folds back current before the die hits the thermal limit, which saves the board trace from a shorted load. The NOPB suffix confirms it is lead-free / RoHS-compliant from the factory.","metaTitle":"LM1117IDT-ADJ/NOPB Adjustable LDO, 800 mA, TO-252-3","metaDescription":"Texas Instruments LM1117IDT-ADJ/NOPB adjustable LDO, 800 mA output, 75 dB PSRR at 120 Hz, -40°C to 125°C, TO-252-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"75dB (120Hz)","Series":"-","Package":"Tube","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"800mA","Base Product Number":"LM1117","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"15V","Voltage Dropout (Max)":"1.2V @ 800mA","Current - Supply (Max)":"10 mA","Voltage - Output (Max)":"13.8V","Supplier Device Package":"TO-252-3","Current - Quiescent (Iq)":"5 mA","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8900","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM1117IDT-ADJ%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM1117IDT-ADJ-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/LM1117IDT-ADJ-NOPB when reusing this data.
