Board layout is important for improving power supply rejection ratio (PSRR) and lowering noise. Figure 5-1, Figure 5-2, Figure 5-3, and Figure 5-4 show the board layout for the HPA177 EVM. The switching nodes with high-frequency noise are isolated from the noise-sensitive feedback circuitry. See the data sheet for more specific layout guidelines.
