LM140K-15 Frequently Asked Questions (FAQ)
-
The LM140K-15 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-15 can supply up to 1A of output current, but it's recommended to derate the output current based on the ambient temperature and input voltage to ensure reliable operation.
-
To protect the LM140K-15 from overheating, ensure good airflow around the device, use a heat sink if necessary, and derate the output current based on the ambient temperature.
-
No, the LM140K-15 is a linear voltage regulator and is not designed for use in switching regulator applications. It's intended for use in linear voltage regulation applications only.
