Yep, the MIC5225 of the pixl has a better (~1/2) dropout figure than the MCP1703 in the MDBT42Q breakout, but that "Very low ground current 29µA", if that's that, is not so good.
The MDBT42Q .pdf says a couple µA in sleep mode, is that right?
It also says it can run from 1.7 .. 3.6V, I could run it straight from 2 big D alkalines in series (3 fully charged .. 2V discharged) and remove the LDO, but, will the LCD still be visible with just two volts? What do you think?
