LM337SP Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM337SP is 40V, but it's recommended to keep it below 35V for reliable operation.
-
To ensure stability, use a minimum output capacitance of 10uF, and a minimum ESR (Equivalent Series Resistance) of 0.5 ohms. Also, keep the input and output capacitors close to the regulator.
-
The LM337SP can regulate properly with a minimum load current of 3.5mA. However, it's recommended to have a minimum load current of 10mA for optimal performance.
-
The LM337SP 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 according to the temperature derating curve in the datasheet.
-
Use a TVS (Transient Voltage Suppressor) diode or a zener diode in parallel with the input capacitor to protect the LM337SP from input voltage transients.
