(1) To ensure stability of the linear regulator, the absolute minimum output capacitance should not be less than 1.0 µF.
(2) Recommended value is 3.3 µF each. Different values are acceptable, provided that the sum of the two is 6.8 µF maximum.
(3) Allows for VOFFSET current measurement
(4) Allows for DMDVCC2 current measurement
