Recommended PCB layout
The STOD03A is a high frequency power switching device and therefore requires a proper
PCB layout in order to obtain the necessary stability and optimize line/load regulation and
output voltage ripple.

In order to minimize ground noise, a common ground node for power ground and a different
one for analog ground must be used. In the recommended layout, the AGND node is placed
