NOTES

1Capacitors C

IN, CO and CP in the test circuit are 4.7 µF with 0.1 Ω ESR.

2See Figure 1 Conditions.

3All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.

4For the adjustable device, a 1% resistor should be used to maintain output voltage tolerance. For both device types, tolerances can be improved by >1% using larger

value and lower ESR capacitors for CO and CP.

Specifications subject to change without notice.
