LM337LMX Frequently Asked Questions (FAQ)
-
The LM337LMX can handle input voltages up to 40V, but it's recommended to keep the input voltage at least 2V higher than the output voltage to ensure proper regulation.
-
The output voltage of the LM337LMX can be adjusted by connecting a resistor divider network between the output pin and the adjust pin. The ratio of the resistors determines the output voltage.
-
The LM337LMX requires a minimum load current of 10mA to regulate properly. If the load current is less than 10mA, the output voltage may not be regulated accurately.
-
The LM337LMX is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
-
To protect the LM337LMX from input voltage transients, it's recommended to add a transient voltage suppressor (TVS) diode or a zener diode in parallel with the input capacitor to clamp the input voltage.
