Variable Power Regulator Using TPS5420

I typically use linear regulators (e.g. 7805, LM317, etc.) in my projects. Linear regulators (especially the low dropout ones) are great when the load is light and input/output voltage difference is small, otherwise you will need a big heatsink as significant amount of power is dissipated as heat. The heat issue was evident in my earlier build of the VFD clock. Given how easy it is to use a switching regulator nowadays, there really is no excuse to settle on a linear regulator in situations like this.
