ProtoDAC TDA1387 X8 project

[OnkelPH]

6.5mA max current for one times 8 is 0.052A. The LM317 is not considered an LDO. It needs 3V minimum difference between voltage in and voltage out.

The LT1963 is an LDO, and can operate with 350mV differential (or even less at low current).

Do you think It can be a good idea to try a breakout GPIO in between the rpi and the IC Q7 too bypass the 5v to the ProtoDAC? and add a LT1963 filter??? If you understand my idea???
