Notes
1Current limit is specified with VOUT = 4.5V.
2Guaranteed by design. Derived from the ISET current ratio, current-limit amplifier and internal set resistor accuraciues.
3Tested with IOUT = 200mA and VSET adjusted until (VIN - VOUT) ജ 0.8V.
4Specifications to -40oC are guaranteed by design, not tested.
