LM3691TL-1.2/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure the output capacitor's ESR is less than 1 ohm. Also, use a minimum input capacitance of 1uF.
  • The maximum output current is 1A, but it's recommended to keep it below 0.8A for reliable operation and to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
  • The operating temperature range is -40°C to 125°C, but the device is only guaranteed to meet specifications between -20°C and 85°C.
