For years—decades, in fact—the NMOS transistor world has been on cruise control. NMOS is naturally faster and its performance has scaled better than PMOS. PMOS has had a cost advantage. But lately, it ...
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 ...
