@726marsh

Would there be an indication of the type of device that would be?  
As items that are in the SOT-23-5 can be many a device type, as shown in the below link.

I think it is a 5 volt to 10 volt regulator.

I think I am ok. I lost my 10 volt power to the plug on the right side and I am hoping this chip will fix that. Unless you have another suggestion. Thank you so much.
