That is a production-line requirement for most automotive Tier-1s — without it, the assembler needs X-ray or a manual inspection step.

The base TPS628110 is a commercial/industrial grade part without AEC-Q100 certification. Pin-compatible and functionally identical, but only the AQ variant is approved for automotive BOMs."},{"question":"Can TPS628110AQWRWYRQ1 be used in 5V to 3.3V conversion?","answer":"Yes. The input range is 2.75V to 6V, so a 5V rail is well within spec. The output is adjustable from 0.6V to 5.5V via an external resistor divider. Setting it to 3.3V is a standard configuration. The 1A output current is sufficient for most MCU, sensor, and transceiver loads in automotive modules."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS628110AQWRWYRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS628110AQWRWYRQ1 when reusing this data.
