LM348N Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM348N is 35V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and keep the input capacitance as close to the regulator as possible.
  • The minimum input voltage required for the LM348N to regulate properly is 2V above the output voltage (e.g., 7V for a 5V output).
  • The LM348N is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or a more temperature-resistant regulator for high-temperature applications.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp to protect the LM348N from input voltage transients and spikes.
