A good PCB layout for optimal thermal performance involves placing the device on a thick copper plane, using thermal vias to dissipate heat, and keeping the thermal path short and direct. A 4-layer PCB with a solid ground plane and a thermal plane is recommended.
To ensure reliable start-up and shutdown, make sure to follow the recommended power-up and power-down sequences, and provide a stable input voltage. Also, ensure that the input voltage rises and falls monotonically, and avoid sudden changes in input voltage.
To minimize EMI and RFI, use a pi-filter (L-C-L) or a common-mode choke at the input, and a ferrite bead or a common-mode choke at the output. Also, ensure that the PCB layout is designed to minimize radiation and susceptibility to external interference.
To optimize the device for low noise and high PSRR, use a low-noise input voltage, minimize the input capacitance, and use a high-quality output capacitor with low ESR. Also, ensure that the device is operated within its recommended operating conditions.
For high-temperature operation, derate the device's power dissipation according to the thermal derating curve provided in the datasheet. Ensure that the device is operated within its recommended operating temperature range, and provide adequate heat sinking and thermal management.
