LM2903AVQDR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2903AVQDR can handle?
  The maximum input voltage for the LM2903AVQDR is 26V, but it's recommended to keep it below 24V for reliable operation.
• Can I use the LM2903AVQDR in a high-temperature environment?
  The LM2903AVQDR is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
• How do I ensure the stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR of 5 ohms or less, and keep the input capacitance to a minimum (less than 1uF).
• What is the minimum input voltage required for the LM2903AVQDR to regulate properly?
  The minimum input voltage required for the LM2903AVQDR to regulate properly is 7.2V for a 5V output and 10.5V for a 12V output.
• Can I use the LM2903AVQDR in a switching regulator application?
  No, the LM2903AVQDR is a linear voltage regulator and is not suitable for use in switching regulator applications.
