Switching and linear power supplies can deliver the same output voltage, but they behave very differently in heat, size, efficiency, noise, and EMC performance. For most industrial systems, a switching power supply is the practical default, while linear regulation still makes sense for low-noise analog rails and precision sensing branches.
