LM317MDT/NOPB 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 x (1 + R2/R1).
-
The minimum load current required is 3.5mA to ensure proper regulation. If the load current is less than this, an additional resistor can be added to the output to ensure regulation.
-
To protect the device from overheating, ensure good thermal design, use a heat sink if necessary, and keep the junction temperature below 125°C. Also, avoid exceeding the maximum power dissipation of 20W.
-
No, the LM317MDT/NOPB is designed to regulate positive voltages only. For negative voltage regulation, consider using a negative voltage regulator like the LM337.
