LM317AEMPX/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
-
You can adjust the output voltage by using a resistor divider network between the output and adjustment pins. The formula is: Vout = 1.25 x (1 + R2/R1).
-
The minimum load current is 3.5mA, but it's recommended to have a load current of at least 10mA for stable operation.
-
The LM317AEMPX/NOPB has an operating temperature range of -40°C to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink and ensure good airflow to keep the temperature below 85°C.
-
You can use a transient voltage suppressor (TVS) diode or a zener diode in parallel with the input capacitor to protect the regulator from input voltage transients.
