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 short and wide traces for the power lines.
Ensure that the output capacitor is within the recommended range (22uF to 47uF), and the input capacitor is at least 10uF. Also, keep the feedback resistors (R1 and R2) within the recommended range (1kΩ to 10kΩ).
The RT8251GQW can handle up to 28V input voltage, but it's recommended to keep it below 24V for optimal performance and reliability.
The RT8251GQW is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability.
The output voltage (Vout) can be calculated using the formula: Vout = (R2 / R1) * (Vin - Vref), where Vin is the input voltage, Vref is the reference voltage (1.25V), and R1 and R2 are the feedback resistors.
