MC78M12ACTG

The MC78M12ACTG is a three-terminal negative linear voltage regulator that is designed to provide fixed output voltage. It is a monolithic integrated circuit designed to provide a regulated negative output voltage of -12V with an input voltage range between -15V and -20V. The MC78M12ACTG features a foldback current limit that decreases foldback current as the output voltage decreases, making it well suited for high surge current applications. It also features output current and thermal regulation for improved stability, as well as low temperature coefficient and low noise characteristics. The combination of these features makes the MC78M12ACTG an ideal choice for use in various applications, such as battery-powered devices, portable devices, and other regulated power applications.

The MC78M12ACTG provides superior performance, stability and reliability due to its advanced design and process technology. It also features low quiescent current and low dropout voltage, which enables it to operate in demanding environments. The device is intended for use in applications that require a regulated output voltage of -12V. It is available in the industry standard TO-252-3 package, which makes it suitable for high volume applications.

In terms of working principle, the MC78M12ACTG uses a negative feedback amplifier with an internal voltage reference to regulate the output voltage. The feedback amplifier is connected to the output of the device, while the internal voltage reference is connected to the input. The feedback amplifier compares the actual output voltage to the reference voltage and adjusts the output voltage accordingly. This causes the output voltage to remain stable, regardless of changes in input voltage and load current. The device is also equipped with over-voltage and over-temperature protection, ensuring safe, reliable operation.

The MC78M12ACTG is typically used in applications that require a regulated output voltage of -12V, such as medical devices, instrumentation, and instrumentation stimulators. It is also ideal for use in battery-powered devices and portable devices due to its low quiescent current and low dropout voltage. Furthermore, the device can be used in applications that require high surge current and thermal regulation, such as automotive and industrial systems. Finally, it is also suitable for use in high-volume applications, thanks to its industry standard TO-252-3 package.

The MC78M12ACTG is a reliable, efficient, and cost-effective solution for providing a regulated -12V output voltage. Its advanced design and process technology provide superior performance, stability, and reliability. It is suitable for use in a variety of applications, from medical devices to automotive and industrial systems. Furthermore, it is available in the industry standard TO-252-3 package, which makes it suitable for high volume applications.
