It comes in a surface-mount SOT-223 package and operates over 0°C to 125°C, making it a fit for commercial and industrial equipment that does not require cold-start below freezing. The fixed output eliminates the feedback divider, saving two resistors and a node on the board. ## Dropout and PSRR — what they mean for the rail Maximum dropout is 1.25 V at the full 1 A load. PSRR runs 60 to 75 dB at 120 Hz. ## Protection and quiescent draw On-chip over-current and over-temperature protection are included. Quiescent current is 5 mA typical, with a maximum supply current of 10 mA. ## Sourcing and lifecycle Product status is Active with ROHS3 compliance. No last-time-buy or obsolescence risk is associated with this part today.","metaTitle":"LMS8117AMP-3.3/NOPB 3.3V Fixed Output LDO, 1A, SOT-223","metaDescription":"Texas Instruments LMS8117AMP-3.3/NOPB is a 3.3V fixed-output LDO regulator rated for 1A with PSRR 60-75 dB at 120 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"60 ~ 75 dB (120Hz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-261-4, TO-261AA","lifecycle_stage":"eol_hot","Current - Output":"1A","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)":"1.25V @ 1A","Current - Supply (Max)":"10 mA","Supplier Device Package":"SOT-223","Current - Quiescent (Iq)":"5 mA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.39","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.39000","currency":"USD"},{"qty":10,"price":"$1.24100","currency":"USD"},{"qty":25,"price":"$1.17840","currency":"USD"},{"qty":100,"price":"$0.96790","currency":"USD"},{"qty":250,"price":"$0.90476","currency":"USD"},{"qty":500,"price":"$0.79956","currency":"USD"},{"qty":1000,"price":"$0.63123","currency":"USD"},{"qty":2000,"price":"$0.59550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d02dfd9246243eb8bff362e479e18965.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LMS8117AMP-3.3/NOPB replace LM1117?","answer":"Both are 1 A fixed-output LDOs in SOT-223, but the LM1117 family has a lower dropout (1.2 V typical at 1 A) and a wider temperature range option. Check the specific LM1117 variant's pinout and thermal performance for your board — the LMS8117AMP-3.3/NOPB is a functional alternative in many 3.3 V fixed-output designs, but verify dropout headroom and operating temperature range for your application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMS8117AMP-3.3-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/LMS8117AMP-3.3-NOPB when reusing this data.
