LM79M12CT/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage for the LM79M12CT/NOPB is 35V, but it's recommended to keep it below 25V for optimal performance and to prevent overheating.
-
The LM79M12CT/NOPB has an operating temperature range of 0°C to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink or thermal management system to keep the junction temperature below 125°C.
-
The output voltage tolerance of the LM79M12CT/NOPB is typically ±4% of the nominal output voltage (12V). To calculate the tolerance, multiply the nominal output voltage by the tolerance percentage (e.g., 12V x 0.04 = ±0.48V).
-
The LM79M12CT/NOPB requires a minimum load current of 5mA to maintain regulation. If the load current is less than 5mA, the output voltage may not be regulated accurately.
-
The LM79M12CT/NOPB is a linear voltage regulator, not a switching regulator. It's not suitable for switching power supply designs, as it would be inefficient and may not provide the required output voltage regulation.
