A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use a low-ESR capacitor for the output capacitor.
Ensure that the output capacitor is properly sized and placed close to the IC. Also, add a 1-2nF capacitor between the VIN and GND pins to prevent oscillation.
The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
Yes, but the IC is only guaranteed to operate up to 85°C. Above this temperature, the IC's performance and reliability may degrade.
The output voltage is determined by the resistive divider network (R1 and R2) connected to the FB pin. Use the formula: Vout = 0.8V x (1 + R2/R1).
