LM79M12CT Frequently Asked Questions (FAQ)
-
The LM79M12CT can handle input voltages up to 35V, but it's recommended to keep it below 25V for reliable operation.
-
To ensure stable and regulated output voltage, make sure to use a suitable input capacitor (e.g., 10uF) and output capacitor (e.g., 22uF) as recommended in the datasheet, and keep the input voltage within the specified range.
-
The LM79M12CT can operate with a minimum load current of 5mA, but it's recommended to have a load current of at least 10mA for stable operation.
-
The LM79M12CT is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
-
Use a transient voltage suppressor (TVS) or a voltage clamp diode in parallel with the input capacitor to protect the LM79M12CT from input voltage transients and spikes.
