LM317T/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM317T is 40V. Exceeding this voltage can cause damage to the device.
-
To ensure stability and prevent oscillations, a minimum output capacitance of 1uF is recommended. Additionally, the input capacitor should be at least 10uF to prevent oscillations.
-
The minimum load current required for the LM317T to regulate properly is 3.5mA. If the load current is less than this, the output voltage may not be regulated accurately.
-
Yes, the LM317T can be used as a constant current source by connecting a resistor between the output and adjustment pins. The current limit is determined by the value of the resistor.
-
To protect the LM317T from overheating, ensure that the device is mounted on a heat sink with a thermal resistance of less than 50°C/W. Also, ensure that the device is operated within the recommended temperature range of -40°C to 125°C.
