11 Layout
11.1 Layout Guidelines
Large transient currents flow in the VIN, VOUT, and GND traces. To minimize both input and output ripple, keep the capacitors as close as possible to the regulator using short, direct circuit traces.
A suggested printed-circuit-board (PCB) routing is shown in Figure 24. The trace lengths from the input and output capacitors have been kept as short as possible.
