Are there any issues using a pair of LDO positive regulators effectively in series to provide a claen low voltage +/- power supply for an analog section of a circuit that is fed from a +/- switch mode supply?
My circuit is powered from a +5, 0, -5V supply and I want the analog section of the circuit to be +2.7, 0, -2.7V. The positive rail is trivial, how can I regulate the negative side of the circuit to 2.7V?
