Foxtech mini 5V 1A switch regulator 7805

The mini switch regulator has similar size to a 7805 linear regulator but much bigger load capacity and much lower heat generation. you can use it to directly replace the linear regulator 7805 on your equipment ,but notice you must at least at a 22 uf or bigger capacitor at the output
