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.

Hi,
I am confused. I thought that this question was answered in this thread:

Please let me know if I missed something. Have a great day!
Best regards,

Hi Coleman,
You're absolutely right, this question has been answered. The original discussion is here as you said:
https://ez.analog.com/message/114815#114815
but somehow its initial question got duplicated above.
In addition, I had answered a different question here:
https://ez.analog.com/message/114819#114819 but my answer appeared as a new post instead.
Apparently, something is going badly wrong with whatever database is driving EngineerZone. I have posted this issue in the EZ Feedback community:

Hi guyz, hmm... it is weird, because I submitted that question and then merely edited my own post, and it seems that for some mysterious reason the topic doubled itself. I believe this thread can be safely removed, since all the questions were answered in the other thread. Probably some glitch in the system.
This question has been assumed as answered either offline via email or with a multi-part answer. This question has now been closed out. If you have an inquiry related to this topic please post a new question in the applicable product forum.
