LM317T/LF01 Frequently Asked Questions (FAQ)
-
The minimum input voltage required for the LM317T/LF01 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/LF01 can deliver is 1.5A. However, it's recommended to derate the current to 1A or less to ensure reliable operation.
-
No, the LM317T/LF01 is designed to regulate positive voltages only. If you need a negative voltage regulator, you should consider using a different device, such as the LM337.
-
The output voltage of the LM317T/LF01 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).
