Caution1. Turn on VIN and VON/OFF at the same time, or turn on VIN first and then VON/OFF.
Turn off VIN and VON/OFF at the same time, or turn off VON/OFF first and then VIN.
2. If absolute maximum rating is not exceeded, you can used this product above the recommended
operating range. However, since a margin with absolute maximum rating decreases, please use
this product after sufficient evaluation.
