For a simple point-of-load rail feeding a 1.1V core, this removes the need for a separate supervisory IC or reset generator. The Enable pin allows the system MCU or power-management sequencer to gate the output. Fixed output means no external resistor divider — the BOM count stays low.","metaTitle":"TLV73311PQDBVRQ1 LDO Regulator, AEC-Q100, 1.1V Fixed Output","metaDescription":"AEC-Q100 qualified LDO.

That qualification covers the stress tests (HTOL, ESD, latch-up, temperature cycling, etc.) that an OEM auditor expects in a PPAP package. The operating temperature range is -40°C to 125°C, suitable for under-hood and cabin applications."},{"question":"Is TLV73311PQDBVRQ1 compatible with 5V input?","answer":"Yes, the maximum input voltage is 5.5V, so a 5V rail is within range. The fixed 1.1V output will regulate from a 5V bus as long as the input stays above the dropout threshold."},{"question":"What is the equivalent or replacement for TLV73311PQDBVRQ1?","answer":"There is no direct pin-compatible second-source listed. Among peers, the TPS70612DBVT offers a 1.2V fixed output at 150mA with reverse-polarity protection, but at half the current and a different output voltage. The TPS7A0313PDBVR provides 1.3V at 200mA with lower quiescent (300 nA typ). Neither is a drop-in replacement — verify output voltage, current rating, and pinout against your board before substituting."},{"question":"Can I order TLV73311PQDBVRQ1 in cut tape or reel?","answer":"Yes, the part is available in Tape & Reel (TR) or Cut Tape (CT) formats. The Q1 suffix on the order code indicates the automotive-qualified variant; the packaging suffix determines reel vs cut-tape delivery."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV73311PQDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV73311PQDBVRQ1 when reusing this data.
