BC857 as a 1.8 regulator transistor for adau1701

Hello everybody, I have been making the schematic for my own 1701 board (yay yay). But since I am not an engineer I am awfully afraid of making any mistake. So I chose BC857 as a 1.8 regulator transistor since it is small and has a huge beta. It seems that this transistor should be fit for the task, but just in case, I wanted to ask, am I right? Is this transistor suitable? Again, I am just very afraid of making a mistake.

The datasheet is here.
