The ADR365BUJZ-R2 is a specialized voltage reference device. This device has been designed primarily for precision-regulated power-supply applications, such as those found in server motherboards and other digital electronics. The device is also well-suited for use as a low-noise voltage reference for analog circuitry.

The ADR365BUJZ-R2 device is an self-contained, high-precision voltage regulator designed for optimization of fixed or adjustable output voltage regulation. Containing an external oscillator and buffered amplifier, it is designed to regulate an output voltage from 0.8V up to 5.5V. The device is specifically designed for voltage control and over-current protection, enabling it to efficiently control output current up to 1.8A.

The device’s internal structure includes built-in auxiliary winding which allows user to setup application specific output requirements. The device features an integrator, output transistors, zener ready rectifiers and a reference circuit. The integrated current sensing circuit allows voltage adjustments to be made by changing the output swing of the reference circuit. The integrated LDO (Low Dropout) regulator provides an extra layer of control and accuracy by providing voltage corrections faster than those achievable by on-board resistors.

The most popular uses of the ADR365BUJZ-R2 device are as a precision voltage regulator for servers and other electronic systems, or as a low-noise voltage reference for analog circuitry. It is a versatile device that has been designed for a variety of applications, including power supply, DC-DC converters, motor control, solar inverters, medical and automotive equipment, and other industrial applications.

The ADR365BUJZ-R2 device’s working principle consists of two components: the Voltage Regulator (VR) and the Voltage Reference Circuit (VRC). The VR is responsible for the regulation of the output voltage and over-current protection, while the VRC provides the necessary reference voltage to the VR, which is then used to control the output voltage. The VRC consists of a voltage reference circuit, a differential amplifier, an error amplifier and an output voltage controller.

The integrated Voltage Reference Circuit provides a stable reference voltage to the VR, allowing it to accurately control the output voltage. It uses an integrator to measure the voltage difference between the reference voltage and the output voltage and then adjust the control parameters accordingly. It also includes an error amplifier and a differential amplifier to further improve accuracy, as well as an output voltage controller. This output voltage controller is responsible for providing a range of output voltage levels for the device.

The ADR365BUJZ-R2 device’s high accuracy and wide output range make it ideal for use in a variety of applications. It is also designed to provide robust protection from transient over-voltage and current flow, providing optimal performance and reliability in a wide range of applications.
