L7987 Frequently Asked Questions (FAQs)

  • The L7987 can handle input voltages up to 45V, but it's recommended to keep it below 40V for reliable operation.
  • Choose an output capacitor with a minimum capacitance of 10uF and an ESR (Equivalent Series Resistance) of less than 1 ohm. X5R or X7R ceramic capacitors are recommended.
  • A minimum input capacitance of 1uF is recommended to ensure stable operation, but a larger capacitance (e.g., 4.7uF) is recommended for high-input-voltage applications.
  • The L7987 is rated for operation up to 150°C, but its performance may degrade at high temperatures. Ensure proper thermal design and heat sinking to maintain reliable operation.
  • Calculate the power dissipation using the formula: Pd = (Vin - Vout) x Iout. Ensure the calculated power dissipation is within the device's rating (typically 1.5W).
