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 140% (typical value) of the maximum

rated “total” current of both outputs.

3. An external inhibit interface should be used to pull the inhibit low or leave it floating. The inhibit pin can be left unconnected if not used.
