Connect each supply pin (VIN, VDD_LDO) directly
to the power or ground planes with a short via. The via is usually placed tangent to the
landing pads of the supply pins with the shortest trace possible.
Make sure the power supply decoupling capacitors
are a small physical size (0402 or smaller) and placed close to the supply pins to
minimize inductance. The capacitors are commonly placed on the bottom layer and share the
ground of the EP (Exposed Pad).
