LM397MFX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the distance between the input and output capacitors as short as possible to minimize inductance.
  • The LM397MFX/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.
  • The minimum input voltage is 7.2V, but it's recommended to keep it above 8V for optimal performance and to prevent dropout.
  • Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Ensure the calculated PD is within the device's thermal limits.
