Page 26 shows a split power supply with capacitor values roughly 10 times greater on the negative side. Anyone understand why?
I think it’s simply because the negative regulator is a different part (L7915 instead of L7815). If you look at the L7915 datasheet, it has the same cap values: 2.2 µF on the input and 1 µF on the output. Maybe the internal circuitry is different enough that different capacitance is required for good performance.
