The AEC-Q100 qualification (series: Automotive, AEC-Q100) means it has passed the stress tests automotive OEMs require — extended temperature cycling, high-temperature operating life, and ESD robustness. If your BOM calls for a 1V rail in a passenger-vehicle or commercial-vehicle ECU, this is the tier to spec.
Housed in an SOT-23-5 (SOT-753) package, it is a surface-mount device. The enable pin gates the output for sequenced power-up or low-power sleep modes.
Listed as Active (current lifecycle stage) and ROHS3 compliant. For a production BOM that needs an automotive 1V LDO, this is a straightforward line item to qualify.
