Rated for -40°C to 125°C ambient. The 12-TDFN exposed-pad package (3x3 mm) requires a thermal land on the PCB.
Status is Active, so there is no end-of-life notice to watch. ROHS3 compliant, which covers the current EU RoHS directive. No lead (Pb) restriction issues for the BOM.
REACH compliance is not separately stated in the available records.
The rated continuous output current is 1A. That is enough for a microcontroller rail, a CAN transceiver, and a handful of sensors — not a main power-stage regulator.
