LM317LZ/LFT2 Frequently Asked Questions (FAQ)
-
The minimum input voltage required for the LM317LZ/LFT2 to operate is 3V above the output voltage. For example, if the output voltage is 5V, the minimum input voltage would be 8V.
-
The output voltage of the LM317LZ/LFT2 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).
-
The maximum current that the LM317LZ/LFT2 can supply is 1.5A. However, the actual current limit may be lower depending on the input voltage, output voltage, and thermal conditions.
-
To protect the LM317LZ/LFT2 from overheating, ensure that the device is properly heat-sinked, and the input voltage is within the recommended range. Also, avoid operating the device at high ambient temperatures or with high output currents.
-
No, the LM317LZ/LFT2 is designed to regulate positive voltages only. If you need to regulate a negative voltage, you would need to use a different voltage regulator, such as the LM337.
