ADP3156–SPECIFICATIONS
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods. Specifications subject to change without
notice.
Dynamic supply current is higher due to the gate charge being delivered to the external MOSFETs.
The trip point is for the output voltage coming into regulation.
