LM2904N Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2904N?
  The maximum input voltage that can be applied to the LM2904N is 26V, but it's recommended to keep it below 20V for reliable operation.
• How do I ensure the LM2904N is stable and doesn't oscillate?
  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.
• What is the minimum input voltage required for the LM2904N to regulate properly?
  The minimum input voltage required for the LM2904N to regulate properly is 7.5V for a 5V output, and 10.5V for a 12V output.
• Can I use the LM2904N in a high-temperature environment?
  The LM2904N is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or a thermally-enhanced package for high-temperature applications.
• How do I protect the LM2904N from input voltage surges or spikes?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the LM2904N from voltage surges or spikes.
