LM317MQDCYRG4 Frequently Asked Questions (FAQ)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.

  • The output voltage can be adjusted by using a resistive divider network between the output and adjustment pins. The formula to calculate the output voltage is Vout = 1.25 * (1 + R2/R1).

  • The LM317MQDCYRG4 requires a minimum load current of 3.5mA to maintain regulation. If the load current is less than this, an additional resistor can be added to ensure proper operation.

  • To prevent overheating, ensure good heat sinking, use a heat sink with a thermal resistance of less than 10°C/W, and keep the ambient temperature below 50°C. Also, avoid exceeding the maximum power dissipation of 20W.

  • No, the LM317MQDCYRG4 is a linear voltage regulator and is not suitable for use in switching power supplies. It's designed for use in linear power supplies and battery-powered applications.
