NOTES
1
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
2
Dynamic supply current is higher due to the gate charge being delivered to the external MOSFETs.
3
The trip point is for the output voltage coming into regulation.
Specifications subject to change without notice.
