Pin 1 orientation and the Enable/Output/Ground assignment follow the common SOT-23-5 convention, so it will drop onto a layout designed for a typical 5-pin LDO. Always confirm the pinout against your PCB layout before soldering."},{"question":"Is LP2981IM5X-5.0 going EOL?","answer":"No. The LP2981IM5X-5.0 is listed with an Active lifecycle status. There is no announced end-of-life or last-time-buy notice for this part."},{"question":"Is LP2981IM5X-5.0 a direct replacement for LP2981IM5X-3.3?","answer":"The LP2981IM5X-5.0 and LP2981IM5X-3.3 are the same regulator family in the same SOT-23-5 package, differing only in fixed output voltage — 5.0V versus 3.3V. They are pin-compatible, so swapping the output voltage is a matter of changing the BOM line, not the PCB layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2981IM5X-5.0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP2981IM5X-5.0 when reusing this data.
