A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the IC.
Use a high-quality output capacitor with low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, ensure the input capacitor is rated for the maximum input voltage.
The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the regulator's stability and output voltage regulation.
Yes, but ensure the junction temperature (Tj) does not exceed 150°C. Use a heat sink or thermal interface material to maintain a safe operating temperature.
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the input from surges or spikes. Ensure the TVS diode is rated for the maximum input voltage.
