The surface-mount SOT-23-3 footprint is compact enough for dense automotive ECU layouts, and the package supports both tape-and-reel and cut-tape options for prototyping or production. The AEC-Q100 qualification package includes the full PPAP documentation set, making it a direct fit for automotive-tier supply chains without additional qualification work.","metaTitle":"TI ATL432LIBQDBZRQ1 Shunt Reference, ±0.5%, SOT-23-3","metaDescription":"Texas Instruments ATL432LIBQDBZRQ1 adjustable shunt voltage reference, ±0.5% tolerance, 2.5-36 V output, AEC-Q100, SOT-23-3.
