I have a design with the enable pin tied to a microcontroller. When I drive the enable low, the output doesn't go to zero but to ~1.2 V. It's still supplying current to some of the devices on my board. Any ideas why this would happen?

Lou,
The current on the EN pin of the IC should be no more than 200nA. I doubt this is causing the 1.2V. Can you please attach a schematic and we'll take a look.
Thanks,

Hello Lou,
I hope this issue has been resolved. It has been sometime from when we last herd from you.
If so, could you please mark this thread as resolved, otherwise, please let me know how I can help out.
