Because of its low cost, it is used in many applications ranging from power management to computer network services. This device is available in a TO-220 package and has a maximum power dissipation of 500 mW.

Application Fields of MC79M12BDTRK

The MC79M12BDTRK voltage regulator is usually recommended for use in applications with low power dissipation, including those that utilize a negative supply voltage. It is suitable for use as a general negative voltage regulator in basically any low current application.Below are some examples of the applications that MC79M12BDTRK can be used to regulate the negative voltage in: 1. Low-noise power supplies 2. Battery-powered equipment 3. Instrumentation devices 4. Handheld or portable equipment 5. Computer peripherals 6. Telecommunications equipment

Working Principle of MC79M12BDTRK

The MC79M12BDTRK regulator consists of three pins and is fairly simple in its operation. The pins are labeled as input, output, and ground. The input pin is used to supply the voltage, while the output pin is used to supply the regulated voltage. The ground pin serves as a return for the current that flows through the circuit.When a negative voltage is applied to the input pin, the regulator will then convert this voltage into the regulated output voltage. This is done by the regulator comparing the input and output voltage and adjusting its internal power transistor, thereby adjusting the output voltage.The MC79M12BDTRK voltage regulator has an adjustable voltage range of -1.25V to -25.5V. It is also output current rated at 1.5A and can operate from a temperature range of -40°C to 125°C.When it comes to safety, the MC79M12BDTRK is fully compliant with the applicable UL and CSA safety standards. This is done by incorporating a thermal shutdown feature and over voltage protection.

Conclusion

The MC79M12BDTRK negative voltage regulator is a low cost and efficient three-terminal regulator who can supply a stable and consistent output voltage over a wide range of current. It is easy to use, inexpensive, and provides a broad adjustable voltage range. The MC79M12BDTRK voltage regulator is a popular choice for many applications where negative voltage is needed.
