LM140K-5.0 Frequently Asked Questions (FAQ)
-
The LM140K-5.0 can handle input voltages up to 35V, but it's recommended to keep the input voltage at least 2V higher than the output voltage to ensure proper regulation.
-
To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) of the capacitor should be less than 5 ohms.
-
The LM140K-5.0 is rated for operation up to 125°C, but the output current should be derated at higher temperatures to prevent overheating. Consult the datasheet for specific derating curves.
-
A transient voltage suppressor (TVS) or a zener diode can be used to protect the LM140K-5.0 from input voltage transients. The TVS or zener diode should be rated for the maximum input voltage and should be placed between the input pin and ground.
-
Yes, multiple LM140K-5.0 regulators can be paralleled to increase the output current, but it's essential to ensure that the output voltages are matched and the input voltages are synchronized to prevent oscillations.
