LM337IMP/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
-
The output voltage can be adjusted by using a resistor divider network between the output and the adjust pin. The formula to calculate the output voltage is Vout = 1.25V * (1 + R2/R1).
-
The minimum load current required is 10mA. If the load current is less than 10mA, the output voltage may not be regulated properly.
-
The LM337IMP/NOPB is rated for operation up to 125°C, but the output current should be derated at higher temperatures to prevent overheating.
-
A capacitor (e.g., 10uF) can be connected between the input and ground to filter out voltage transients. Additionally, a voltage clamp (e.g., a zener diode) can be used to protect the regulator from voltage spikes.
