LM66200: Vin power change

Part Number: LM66200

Hi 

I have question of Vin power change.

Test conditions: Vin1=5.4V, Vin2=5V

The power-on priority is Vin2 first. Vout seems to be affected, as shown below

The power-on priority is Vin1 first. Vout power is perfect.


* High potential (5.4V) replaces low potential (5V). The output voltage may be affected.

* This phenomenon is caused by internal MOS switching?
