Notes

1. guaranteed by characterization test and/or analysis. Not a production test.

2. Dual outputs: The over-current limit will trigger when the sum of the currents

from both outputs reaches 125% (typical value) of the maximum rated “total”

current of both outputs.

3. An external inhibit interface should be used to pull the inhibits low or leave them

floating. The inhibit pins can be left unconnected if not used.
