LM2901DR Frequently Asked Questions (FAQ)
-
The LM2901DR can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
-
To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be less than 5 ohms.
-
The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation and to prevent overheating.
-
The LM2901DR is designed for low-current applications (up to 1A). For high-current applications, consider using a different voltage regulator or adding an external pass transistor to handle the increased current.
-
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the input from voltage transients and spikes.
