LM317T Frequently Asked Questions (FAQ)
-
The minimum input voltage required for the LM317T to operate is 3V above the output voltage. For example, if the output voltage is 5V, the minimum input voltage would be 8V.
-
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 maximum current that the LM317T can supply is 1.5A. However, it's recommended to derate the current to 1A or less to ensure reliable operation.
-
No, the LM317T is designed to regulate positive voltages only. If you need a negative voltage regulator, you should use a different IC, such as the LM337.
-
The output voltage of the LM317T can be adjusted by using a resistive divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the reference voltage (1.25V).
