Your looking for the Export to CAD tool. This will create one or more CAD drawing files based on the values contained in one or more input feature classes or feature layers and supporting tables. Also look at the Add CAD Fields command to prepare your FC for output.
Output formats supported included DGN (V8 Microstation), DWG (version 2013), or DXF (version 2013).
If you already have a target drawing you will want to add the GIS data to, consider using the existing drawing as your 'seed' file.
This is available with Basic, Standard and Advanced licenses.
