LM337T Frequently Asked Questions (FAQ)
-
The LM337T 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.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the output capacitor close to the regulator. Also, use a low-ESR capacitor to minimize oscillations.
-
The LM337T can regulate properly with a minimum load current of 3.5mA. However, it's recommended to have a minimum load current of 10mA to ensure proper regulation.
-
The LM337T is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and voltage according to the temperature derating curve in the datasheet.
-
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp to protect the LM337T from input voltage transients. You can also add a series resistor and capacitor to filter out high-frequency noise.
