Introduction

The MC7815CTG is a 5V, three-terminal, positive-voltage regulator integrated circuit. It is an ideal choice for providing well-regulated and highly accurate voltage supply to modern digital systems.

Application field

The MC7815CTG is well-suited for a wide range of applications. It suits those which require a stable and highly accurate voltage supply. These include, flash memory, standard buses, digital signal processors, and microprocessor cores. It is ideal for supplying the power supply for low-power portable equipment. This includes devices such as PDAs and Digital Cameras. It is also suitable for PC motherboards and card-edge applications. This is due to its excellent stability and accurate voltage regulation. It is designed using current limited architectures which protect the regulator from overloading and damage.

Working principle

The MC7815CTG is a three-terminal positive-voltage regulator integrated circuit. It has a fixed voltage output of 5V, and is designed to be used with either a ceramic or a tantalum capacitor as the output filter capacitor. Its purpose is to ensure that the output voltage is kept in tight regulation.The MC7815CTG is designed to provide a precise and well-regulated output voltage from a wide range of input voltages. This is accomplished by self-adjustment of its internal circuitry, allowing the output voltage to remain within close tolerance.The MC7815CTG is also designed for low quiescent power consumption. This is important for battery-powered applications and saves energy in other applications. The quiescent current draw is typically less than 1mA and is typically less than 40mA at full load.The MC7815CTG can operate from an input voltage range between 6V and 30V. It has an internal thermal protection control which ensures that the device\'s temperature remains within safe limits during a fault or overload condition.

Conclusion

The MC7815CTG is a simple and reliable three-terminal positive-voltage regulator integrated circuit. It is designed to provide well-regulated and highly accurate output voltages, while consuming very low quiescent current. It is particularly suited to low-power portable equipment, PC motherboards, and card-edge applications. Its internal circuitry ensures accurate voltage regulation, making it an ideal choice for modern digital systems.
