Share DVDD between DSPs

Hello again, how are you?

 

I have a design that has two ADAU1701. Currently, each one has its transistor that regulates DVDD down to 1.8V by utilizing the pin VDRIVE (default configuration). This transistor is a BCP69T1G, so it is a 1A transistor, oversized for a single DSP. Because of board layout size, I was wondering if I could simply remove the transistor of one of the two DSPs, and then get the 1.8V from the other DSP that still has the transistor? Would that be ok?

 

Thank you!

 

Best Regards
