LDOs are so common inside portable devices, state of the art power management integrated circuits (PMICs) for smartphones and other portable devices include over a dozen LDOs. To know which LDO you ...
In the last few blogs I have been spending a fair amount of time looking at various performance measurements for LDOs (see Measuring LDO Noise Spectral Density for a Novice, Measuring LDO Power Supply ...
In our previous post Low Power LDO Design Techniques for Really Small Profile Applications, Part 1, we reviewed LDO design tradeoffs using an NMOS pass transistor. This design approach is proven good ...
