Specifications subject to change without notice.
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
Dynamic supply current is higher due to the gate change being delivered to the external MOSFETs.
The trip point is for the output voltage coming into regulation.
