Sometimes I feel that the success that IC vendors have had at packing amazingly good performance and useful features into power-supply regulator ICs -- whether low dropout (LDO) or a switcher -- has worked against them.
Why? As a result of doing such a good job, these critical components often don't get the attention, consideration, or respect they should. After all, without these regulators, most designs would be struggling, trying to work properly with power rails that had the wrong local characteristics (nominal voltage, noise, accuracy, configuration, etc.), even when sufficient bulk power was available on the board.
