LM2904D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2904D can handle?
  The maximum input voltage for the LM2904D is 30V, but it's recommended to keep it below 25V for reliable operation.
• Can I use the LM2904D in a high-temperature environment?
  The LM2904D is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink or thermal management system to keep the junction temperature below 125°C.
• How do I ensure the stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. You can also add a 10nF capacitor in parallel with the output capacitor to improve stability.
• What is the minimum input voltage required for the LM2904D to regulate the output voltage?
  The minimum input voltage required for the LM2904D to regulate the output voltage is typically 2V above the output voltage. For example, for a 5V output, the minimum input voltage would be 7V.
• Can I use the LM2904D in a switching regulator application?
  No, the LM2904D is a linear voltage regulator and is not designed for use in switching regulator applications. It's intended for use in linear voltage regulation applications only.
