NOTES

1Speciﬁcations to –40

°C are guaranteed by design, not tested.

2Guaranteed by design. Derived from the I

SET current ratio, current-limit ampliﬁer and external set resistor accuracies.

3Tested with I

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

0.8 V.

Speciﬁcations subject to change without notice.
