LM2991S/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • Use a 10uF or larger output capacitor with an ESR of 0.1 ohms or less, and a 1uF or larger input capacitor with an ESR of 1 ohm or less.
  • The minimum input voltage required is 7.5V, but it's recommended to keep it above 8V for reliable operation.
  • Yes, but the device is only specified for operation up to 125°C. Above this temperature, the device's performance and reliability may degrade.
  • Use a TVS (transient voltage suppressor) diode or a zener diode with a voltage rating higher than the maximum input voltage to clamp the input voltage.
