Specifications subject to change without notice.
REV. B
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
Guaranteed by design, not tested in production.
If SYNC function is used, then f
V
Accuracy guaranteed by ISET input, programming function accuracy specification.
System current sense is active during shutdown.
Load current is supplied through SYS+ pin.
Guaranteed output current from 0 to min specified value to maintain regulation.
