LM2940SX-5.0 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2940SX-5.0 is 26V, but it's recommended to keep it below 20V for reliable operation.
-
To ensure the output voltage is exactly 5.0V, use a 10nF ceramic capacitor on the output pin and a 10uF electrolytic capacitor on the input pin. Also, make sure the input voltage is within the recommended range.
-
The minimum input voltage required for the LM2940SX-5.0 to function properly is 7.5V, but it's recommended to keep it above 8V for reliable operation.
-
The LM2940SX-5.0 is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to prevent overheating. Use a heat sink if necessary.
-
Use a TVS diode or a transient voltage suppressor on the input pin to protect the LM2940SX-5.0 from input voltage transients.
