Do I always have to use a ballast transistor with the built in CAN physical layer?

I have a design that is operating on a regulated 5V supply and the design is space constrained.  So the PCB area is very small.  Adding a recommended ballast transistor to the design for CAN support does not fit very well into the design.  Do I always have to use a ballast transistor with the built in CAN physical layer?  Can I provide a regulated 5V supply to VDDC for power?
