Notes:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2) V DO = V IN -V O when V O decreases by 1.5% of its nominal output voltage with V IN = V O +0.8V.
(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.
