STLED25 Application information
Doc ID 022323 Rev 3 21/30
7.2 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.
