Powering MKL26Z128VFM4

I'm working on a design using the MKL26Z128VFM4. I understand it has a built-in 5V to 3.3V regulator, but I don't want to use it. Can I simply leave the Vregin pin and the Vout33 pin disconnected and supply 3.3V to the Vdd and Vdda pins?

The datasheet does not seem to provide any powering details.

Hello Wilson,

If you will not be using USB on your application, you may leave the USB regulator (VREGIN) and VOUT33 pins floating.

I hope this information helps!
