A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output tracks as short as possible and use a common mode choke to reduce EMI.
Ensure that the output capacitor is properly sized and placed close to the IC. Also, add a 10nF capacitor between the VCC pin and GND to filter out high-frequency noise.
The maximum allowed input voltage ripple is 1% of the input voltage. Exceeding this may affect the regulator's performance and stability.
Yes, but ensure that the junction temperature (TJ) does not exceed 150°C. Use a heat sink or thermal pad to dissipate heat if necessary.
The output voltage tolerance is ±2% of the nominal output voltage. Calculate the tolerance by multiplying the nominal output voltage by 0.02.
