Re: BC857 as a 1.8 regulator transistor for adau1701

Hi Bob! Yes, I read as much as I could about the layout and making it fine is really hard. The good news is that I have already built the prototype of the whole device on a breadboard and it works somehow, though, with some noises and other "unpleasantnesses".  But I hope for the best. Of course soldering all those 201 etc. parts would be quite problematic, but I have no choice, so it must be done. The good news also is that the layout for the power supply is ready and the supply, especially lo-to-high voltage (I need about 400v there), which keeps it stable independent of the battery fluctuations is quite difficult to make especially with no any experience in the area and virtually no ready examples.
