LM2990S-12 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2990S-12 is 40V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure a stable output voltage, make sure to use the recommended output capacitor (10uF or larger) and input capacitor (1uF or larger) as close to the device as possible, and keep the input voltage within the recommended range.
  • The minimum input voltage required for the LM2990S-12 to regulate the output voltage is 14.5V, but it's recommended to keep the input voltage at least 2V above the output voltage for reliable operation.
  • The LM2990S-12 is rated for operation up to 125°C, but the output current may need to be derated at higher temperatures to prevent overheating. Consult the datasheet for thermal derating curves.
  • To protect the LM2990S-12 from input voltage transients, use a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input, and ensure the input capacitor is rated for the maximum input voltage.
