LM2984CT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2984CT?
  The maximum input voltage that can be applied to the LM2984CT is 26V, but it's recommended to keep it below 24V for reliable operation.
• Can I use the LM2984CT as a high-current regulator?
  While the LM2984CT can handle high currents, it's not recommended for high-current applications (>3A) due to thermal limitations. For high-current applications, consider using a heat sink or a more suitable regulator like the LM338.
• How do I choose the correct output capacitor for the LM2984CT?
  Choose an output capacitor with a low ESR (Equivalent Series Resistance) and a value between 10uF to 100uF. A 22uF or 47uF ceramic capacitor is a good starting point. Ensure the capacitor is rated for the output voltage and can handle the ripple current.
• What is the minimum input voltage required for the LM2984CT to regulate the output voltage?
  The minimum input voltage required for the LM2984CT to regulate the output voltage is typically around 2.5V above the output voltage. For example, if the output voltage is 5V, the minimum input voltage should be around 7.5V.
• Can I use the LM2984CT in a switching regulator configuration?
  No, the LM2984CT is a linear regulator and not designed for switching regulator configurations. It's intended for use as a low-dropout linear regulator.
