It is designed to supply a low ripple and low noise regulated output voltage with a maximum dropout voltage of 400mV. In addition, the device features an adjustable current limit and over temperature protection.

Application Field

The ADP7104ARDZ-3.0-R7 is particularly well suited for applications such as wireless modules, industrial and consumer electronics systems, digital cameras, and communication equipment. This linear voltage regulator is particularly suitable for automotive applications due to its wide input voltage range and low power consumption. The device also provides excellent ripple rejection in most noise-sensitive designs, making it very suitable for audio applications.

Working Principle

The ADP7104ARDZ-3.0-R7 works by regulating the input voltage to a given voltage level, thus providing a much better regulated and stable power supply. This device utilizes a P-channel MOSFET to regulate the output current. The MOSFET is connected to a feedback circuit, which is set to regulate the output voltage to the predetermined level. The P-channel MOSFET ensures that the current is constant, and that the output voltage is maintained constant as long as the load current is below the overcurrent limit. In addition, this voltage regulator features a thermal shutdown protection when it detects that the power dissipation has reached the maximum limit. This will help protect the voltage regulator and the rest of the system.

The device also features an adjustable current limit and can be used to protect against short-circuits. In addition, the device has a high ripple rejection, making it suitable for applications with a lot of noise. The device can also be used in applications requiring either a fixed or an adjustable output voltage, making it a very versatile and reliable power solution.

In summary, the ADP7104ARDZ-3.0-R7 is a high performance and reliable three-terminal linear voltage regulator suitable for a wide range of applications. With its wide input voltage range, excellent ripple rejection and adjustable current limit, it is a great choice for many power management projects.
