Notes:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2) VDO = VIN -VO when VO 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 VFB exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the error ampli er and connects VFB
instead.
