2, Circuit diagram :
Note 1: The blue thick line is the power trace, C1 input capacitor and C3 output capacitor must not be omitted. At the same time C1,C2 should be placed next to 4 pins, as close as possible.
Note 2: The red thick line is the power ground, the main points of the drawing board: to bewide, the shorter the distance between the connecting loops at each point.
