[7] Output transition rate: Three modes of Fast, Normal, and Slow are available, allowing users to adjust according to load characteristics to achieve appropriate setup time or stability. This feature only supports switching the output transition rate when OUTPUT is set to OFF
[8] The Fast mode may produce a large overshoot under different ranges or load conditions. For overshoot-sensitive devices, it is recommended to use normal or Slow mode. mode
