1 If V IN is a 4.75 to 5.5 V supply, connect VIN to VREG externally
2 Err = [I O UT (min or max) – I OUT (av)] / I OUT (av), where I OUT (av) is the average of 3 output current values.
3 In daisy-chained applications, t SU(LI) must be increased for the quantity of pixels in the chain (see Application Information section).
