MC78M05ACDTRK: Application Field and Working Principle

MC78M05ACDTRK is a Positive Voltage Regulator of the Linear Voltage Regulator category. It is designed to convert unregulated voltage sources into a regulated output voltage. With the moderate output current and insulated package, it is suitable for applications such as local on-card regulation, battery-powered equipment, other low-voltage current regulator applications and simple power supplies.

The MCP78M05ACDTRK features an adjustable output voltage from 1.2 volts to 5.5 volts. It has an Output Current limit of 500mA, a maximum Dropout voltage of 1.2V with an operating temperature from −40°C up to +125°C.

The MC78M05ACDTRK operates by comparing an internal reference voltage with an input from a voltage divider network external to the device. The input voltage is regulated by the voltage comparator which keeps the regulator output at a constant level. The line regulation is the maximum change in output voltage for a given change in input voltage; this is also known as the load regulation.

The internal protection features are designed to guard the unit against overvoltage, undervoltage, and overheating. The MC78M05ACDTRK has current-limiting protection and overvoltage protection. The overvoltage protection circuit will protect the device from input voltage spikes and transients.

The MC78M05ACDTRK can be used in a wide range of applications, such as central office power systems, mainframe computers, telecom power supplies, PC power supplies, automotive electronic systems and many other electronic products needing regulated power.

The MC78M05ACDTRK is available in an 8-pin Dual-in-Line insulated package and is rated to operate over a temperature range of −40°C to +125°C. It is designed to operate down to a supply voltage of 4V and up to a maximum supply voltage of 28V. It also has a shutdown control pin that can be used to deactivate the device when the voltage falls below a certain threshold, making it ideal for low-powered applications.

The MC78M05ACDTRK has a wide range of features that make it ideal for applications requiring low-voltage, high-accuracy power supply regulation. These features include a high start-up current capability, low dropout voltage, low power dissipation, wide operating voltage range, tight line regulation, low-noise operation, short-circuit protection, and thermal shut-down.

The MC78M05ACDTRK is highly efficient and reliable, making it suitable for many types of applications. The device incorporates a fixed reference voltage and offers excellent line regulation, making it ideal for home electronics, medical instruments, and other applications that require precision regulation of an output voltage.

In summary, the MC78M05ACDTRK is a high quality, cost-effective Voltage Regulator which offers low-voltage, high-accuracy power supply regulation. It has a wide operating voltage range and good line regulation, making it suitable for a variety of applications. The device also features protection circuits that guard against overvoltage, undervoltage, and overheating, ensuring reliable operation in challenging environments.
