NOTES
1Specifications to –40°C are guaranteed by design, not tested.
2Guaranteed by design. Derived from the ISET current ratio, current-limit amplifier and external set resistor accuracies.
3Tested with IOUT = 200 mA and VSET adjusted until (VIN – VOUT) ജ 0.8 V.
Specifications subject to change without notice.
