PMIC - Voltage Regulators - Linear
The MC7809CD2TG is a three-terminal adjustable output voltage regulator with built-in linear current limiting, thermal shutdown and power pass transistor for various application fields. Due to its suitability for a wide range of applications, it is used in a variety of systems including automotive and industrial applications.
The MC7809CD2TG is an adjustable output voltage regulator with an internal limit current protection, thermal shut-down, and a power pass transistor. The main feature of this series is the ability to achieve an output voltage that is adjustable over a wide range, between 8V and 9V. It has an internal voltage reference that is designed to keep the output voltage constant even when the input voltage changes. The output voltage can also be adjusted by using the external control pin.The MC7809CD2TG also has built-in current-limiting protection, thermal shut-down protection and power-pass protection. This prevents the voltage regulator from overloading the output and protects it from damage due to excessive current or thermal conditions. The power pass protection allows the regulator to deliver power to the load in the event of a short circuit or other over-current condition. This makes the MC7809CD2TG suitable for various industrial and automotive applications.The working principle of the MC7809CD2TG is quite simple. The voltage regulator is a three-terminal device with two input pins and one output pin. The input pins are connected to a source of an AC or DC voltage, and the output pin is connected to the load. The voltage regulator has an internal voltage reference, which keeps the output voltage constant, even if the input voltage changes. This is done by controlling the amount of current that flows through the output transistor. When the current through the output transistor exceeds the current limit of the voltage regulator, the output transistor will be turned off to prevent further damage. The MC7809CD2TG is widely used in multiple applications such as:
• Automotive
• Industrial
• Power Supply
• Logic Interface
• Surge Protection
• Battery Chargers The MC7809CD2TG is an economical and efficient voltage regulator for applications that require a stable and adjustable output voltage, thermal and current protection features. It is reliable, efficient, and has a long operating life. In conclusion, the MC7809CD2TG is a three-terminal adjustable voltage regulator with internal linear current limiting, thermal shutdown, and power pass transistor protection, which makes it suitable for a wide range of application fields. It is an effective and economical solution for many applications such as automotive, industrial, power supplies, logic interface, surge protection, and battery charging. Its working principle is straightforward, and it provides a reliable and efficient source of power for many applications.
