LM2990T-12 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2990T-12 is 40V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure a stable and regulated output voltage, make sure to use the recommended output capacitor value (10uF) and keep the input voltage within the recommended range. Also, ensure good thermal management and minimize noise on the input and output lines.
  • The minimum input voltage required for the LM2990T-12 to operate is 14.5V, but it's recommended to keep it above 15V for reliable operation.
  • The LM2990T-12 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • To protect the LM2990T-12 from input voltage surges and spikes, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to limit the voltage to within the recommended range.
