LM3478MM/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM3478MM/NOPB is 18V. Exceeding this voltage may cause damage to the device.
-
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1 ohm or less, and to place the capacitor close to the output pin of the device.
-
The maximum output current that the LM3478MM/NOPB can provide is 500mA. Exceeding this current may cause the device to overheat or fail.
-
To protect the LM3478MM/NOPB from overheating, it is recommended to provide adequate heat sinking, such as a copper plane or a heat sink, and to ensure good airflow around the device.
-
The LM3478MM/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
