Figure 1. Typical Application Circuit

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.
