LB1938FA-AH Frequently Asked Questions (FAQs)

  • 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 ceramic capacitor is rated for the maximum output voltage and has a low ESR. X5R or X7R dielectric types are recommended.
  • Calculate the power dissipation using the formula: Pd = (Vin - Vout) x Iout. Ensure the regulator's power dissipation is within the specified limits to prevent overheating.
