It provides a ±1% tolerance reference voltage adjustable from 2.5 V up to 36 V, with a low cathode current of 80 µA that keeps quiescent draw minimal in always-on ECU circuits.
Supplied in a SOT-23-3 package (TO-236-3 / SC-59 equivalent), surface-mount. The three-pin footprint is standard across the ATL431 family, so a board layout for the base part number accepts this variant without changes.
Yes, it is listed under the Automotive, AEC-Q100 series. The qualification covers the stress and reliability tests required for automotive-grade components.
The tolerance is ±1%.
The cathode current is 80 µA typical.
It is supplied in a SOT-23-3 package (also listed as TO-236-3 or SC-59).
