Notes

1Current limit is specified with V

OUT = 4.5V.

2Guaranteed by design. Derived from the I

SET current ratio, current-limit amplifier and internal set resistor accuraciues.

3Tested with I

OUT = 200mA and VSET adjusted until (VIN - VOUT)

0.8V.

4Specifications to -40oC are guaranteed by design, not tested.

(Specification for either channel 1 or channel 2, VIN = +5.0V, TA = -40 to +85

oC, unless otherwise noted.)
