LM2990T-12/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage is 40V, but it's recommended to keep it below 30V for reliable operation.
-
To ensure stable output voltage, use a minimum of 10uF capacitor at the output and a 0.1uF capacitor at the input. Also, ensure the input voltage is at least 2V above the output voltage.
-
The maximum current that the LM2990T-12/NOPB can supply is 3A, but it's recommended to keep it below 2.5A for reliable operation.
-
To protect the LM2990T-12/NOPB from overheating, ensure good airflow around the device, use a heat sink if necessary, and keep the junction temperature below 125°C.
-
The LM2990T-12/NOPB is rated for operation up to 125°C, but its performance may degrade at high temperatures. Use a heat sink and ensure good airflow to keep the junction temperature below 125°C.
