A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. Keep the thermal path short and use a thermal pad to connect the IC to the ground plane.
Use a high-precision voltage reference, such as a 1% or 0.5% resistor divider network, and ensure the output capacitor is of high quality and suitable for the output voltage and current requirements.
The maximum input voltage is 26V, but it's recommended to keep it below 24V for optimal performance and reliability.
Yes, but ensure it's a high-quality, low-ESR ceramic capacitor with a voltage rating suitable for the output voltage. Avoid using ceramic capacitors with high ESR or those that are prone to voltage coefficient effects.
The output current capability is dependent on the input voltage, output voltage, and thermal conditions. Use the datasheet's thermal derating curves and output current vs. input voltage graphs to determine the maximum output current for your specific application.
