That matters when the input comes from a rectified AC rail or a switching pre-regulator — the LDO cleans the supply for sensitive analog loads such as op-amp front ends, data converters, or audio circuits. ## Dropout and protection — the operating margins Maximum dropout voltage is 1.2 V at 800 mA output, so the input must stay above 6.2 V to maintain regulation at full load. The input is rated up to 15 V absolute maximum. Built-in over-current and over-temperature protection guard against output shorts and thermal runaway in high-ambient or high-load conditions. Buyers should evaluate a form-fit-function replacement from the broader LM1117 family, noting that package and pinout differences must be verified against the target PCB footprint.","metaTitle":"LM1117LDX-5.0/NOPB LDO Regulator, 5V Fixed, 800mA, 8-WDFN","metaDescription":"Texas Instruments LM1117LDX-5.0/NOPB LDO voltage regulator, fixed 5V output, 800mA, PSRR 75dB at 120Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"75dB (120Hz)","Series":"-","Package":"Tape & Reel (TR)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Obsolete","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":"0°C~125°C","Voltage - Input (Max)":"15V","Voltage Dropout (Max)":"1.2V @ 800mA","Current - Supply (Max)":"10 mA","Voltage - Output (Max)":"-","Supplier Device Package":"8-WSON (4x4)","Current - Quiescent (Iq)":"5 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f7a4a08ab916aa4ed597c3c1d9ab0eb4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM1117LDX-5.0%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM1117LDX-5.0-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/LM1117LDX-5.0-NOPB when reusing this data.
