LM2902KDR Frequently Asked Questions (FAQ)
-
The LM2902KDR can operate from -40°C to 125°C, but the recommended operating temperature range is -20°C to 85°C for optimal performance.
-
To ensure stability, use a minimum output capacitance of 10uF, and ensure the output capacitor has an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, place the output capacitor close to the regulator output pin.
-
The minimum input voltage required is 7.5V for the 5V output version, and 10.5V for the 12V output version. However, it's recommended to use an input voltage at least 2V higher than the output voltage for optimal performance.
-
The LM2902KDR is designed for low-to-medium current applications. If you need to supply high currents, consider using a more suitable voltage regulator, such as the LM2940 or LM2990, which can handle higher currents.
-
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to protect the regulator from voltage transients. Additionally, consider adding a fuse or a current limiter to prevent overcurrent conditions.
