Notes:
(1) Low duty cycle pulse testing with Kelvin connections required.

-V
O
when V
O
decreases by 1.5% of its nominal output voltage.
(3) Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this requirement.
(4) Guaranteed by design.
(5) When V
FB
exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the error ampli er and connects V
FB
instead.
