I've got a device that has 3.3V and 1.8V power inputs. I'm providing 3.3V directly and 1.8V via an LDO regulator. The device requires that there is at least a 10ms delay between the 3.3V (first) and 1.8V (second) supplies on power up. It's tempting to do the lazy way and buy a 1.8V regulator with a…
