A good PCB layout for the BU9795AFV-E2 should prioritize thermal dissipation. Place the IC near a thermal pad or a heat sink, and ensure good copper coverage around the IC. Avoid routing high-current traces near the IC to minimize thermal resistance.
To ensure stable operation with a high-ESR output capacitor, add a 1-10nF ceramic capacitor in parallel with the output capacitor to reduce the effective ESR. This helps to improve the overall stability of the regulator.
A 10-22uF X5R or X7R ceramic capacitor is recommended for the input capacitor. This type of capacitor provides low ESR and high ripple current capability, ensuring stable operation and minimizing voltage drops.
To protect the regulator from input voltage surges or spikes, add a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor. This helps to clamp the input voltage and prevent damage to the regulator.
The BU9795AFV-E2 is rated for operation up to 105°C ambient temperature. However, for reliable operation, it's recommended to keep the ambient temperature below 85°C to ensure a sufficient margin for thermal derating.
