It's a pity that this part is NRND any more. It took a while to learn it a bit...
Anyway, I need to find out which is a proper ground to connect REGN capacitor to. In typical application schematic and in EVM it is connected to analog ground, but if REGN pin powers nothing but MOSFET drives it would better have been connected to power ground, so as to minimize loop area. Please clarify this point.
