when the customer give PVDD=19V, and make PDN/ low, the DVDD has output voltage about 1.8V, this impact other circuits at start-up stage.
can you explain why DVDD has a output voltage when PVDD=19V and PDN/ is low?

Hi Eric
There's a lot of LDO inside of our devices, and the circuit not totally isolate from each other. This voltage they test out shouldn't have a very large power, also the PVDD and DVDD usually power up together. What trouble are they seeing for now?
