LM7815ACT is a 3-terminal voltage regulator IC with 2A output current capability. It comes in the TO-220 three-pin package, and features the 78xx family pinout configuration. Designed for low power FM and TV broadcast equipment, this device does everything from keeping clean output voltage to preventing damage to the load or power source. Its wide input range and fast transient response also make it well-suited as a versatile linear voltage regulator in AC power supplies.

The LM7815ACT is an easy-to-use, low cost, highly reliable linear voltage regulator with a wide variety of applications. It is a type of Positive Voltage Regulator (PMIC) and its output current rating is 2A with an output voltage range of 15V to 22V. It is a three-terminal device and its pinout consists of three pins: IN (Input), OUT (Output) and GND (Ground).

The LM7815ACT uses a 3-terminal design for better Thermal and Electrical Performance. The TO-220 three-pin package, which is a low-cost option for commercial applications, features a flat top surface and low profile body. The LM7815ACT is a monolithic integrated circuit with built-in over temperature protection and current limiting.

The LM7815ACT is stable in operation and provides excellent electrical performance. It offers excellent line regulation, low temperature coefficient and low output noise. The output voltage from the device is fully adjustable from 1.25V to 22V, and the device is well-suited for use in Positive Voltage Regulation applications. The LM7815ACT also offers a wide range of features designed to improve reliability, such as full thermal protection, reverse polarity protection, over-current protection and over-voltage protection.

The external components which are needed for the regulation are minimal. The LM7815ACT offers a wide input range from 8V to 24V and has a fast transient response time. Its low quiescent current makes it a good choice for battery-operated applications.

The working principle of the LM7815ACT is based on the classic regulating mechanism used in linear voltage regulators. The voltage regulator uses an internal reference voltage set by its resistor divider network and compares it with the output voltage. When it detects an imbalance, it adjusts the amount of power delivered to the output to maintain the reference voltage. This adjustment is done through the adjustment of a series transistor, which acts as a variable resistor. When the output voltage is lower than the reference, the output current is increased, and when the output voltage is higher than the reference, the output current is decreased.

The LM7815ACT is widely used in a wide range of applications, from battery chargers and power adapters to AC power supplies and audio amplifiers. It is also suitable for consumer electronics such as DVD players, TV sets, digital cameras and other consumer audio/visual equipment.
