LM1117MPX-1.8/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 13.5V for reliable operation.
  • The LM1117MPX-1.8/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
  • Use a 10uF or larger output capacitor with an ESR of 0.05 ohms or less to ensure stability. Also, ensure the input voltage is at least 2V above the output voltage.
  • The LM1117MPX-1.8/NOPB is not a low-dropout regulator. It requires a minimum input-to-output voltage differential of 1.5V to maintain regulation. For low-dropout applications, consider using a different regulator.
  • Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the regulator from voltage transients and spikes.
