Input and output capacitor
Recommended PCB layout
The STLED25 is a high-frequency power switching device, so it requires a proper PCB
layout in order to obtain the necessary stability and optimize line/load regulation and output
voltage ripple. Input and output capacitors must be as close as possible to their relative pins.
