It is important to connect the GND pin, the input
bypass-capacitor ground lead, and the output filter
capacitor ground lead to a single point (star ground
configuration) to minimize ground noise and improve
regulation. Also, minimize lead lengths to reduce stray
capacitance, trace resistance, and radiated noise, with
preference given to the feedback circuit, the ground
circuit, and LX_. Place feedback resistors R1–R4 as
close to their respective feedback pins as possible.
Place the input bypass capacitor as close as possible
to AVCC and GND.
