MC78T12 12V 3A Voltage Regulator

This is a +12V 3A fixed voltage regulator in a TO - 220 package. It features a through - hole active mount type with solder legs. The regulator has 3 legs with a diameter of 0.8mm and a leg distance of 2.54mm. Its case is black. The unique marking code is MC78T12, a number - type code. It can operate up to a max temperature of 125°C. With a positive polarity, it has an output voltage of 11.5V - 12.5V and an input voltage range of 12V - 35V. The maximum current is 3A. It comes with a 3 - month warranty.

Using this voltage regulator is easy. First, make sure the input voltage is within the 12V - 35V range. Then connect it to your circuit using the through - hole solder legs. The regulator will then provide a stable output voltage between 11.5V and 12.5V at a maximum current of 3A. When handling the regulator, avoid exposing it to temperatures above 125°C as it may damage the device. Keep the regulator clean and dry. If you notice any abnormal behavior, such as overheating or inconsistent output, check the connections and input voltage. For any issues, refer to the 3 - month warranty for support.
