ADR127AUJZ-R2

PMIC - Voltage Reference

ADR127AUJZ-R2 is an integrated circuit created by Analog Devices, a semiconductor device manufacturer. It is a 3-Terminal Adjustable Precision Shunt Regulator, which is part of a line of Programmable Logic Integrated Circuits (PLI), more commonly known as Power Management Integrated Circuits (PMICs). ADR127AUJZ-R2 is classified as a Voltage Reference, meaning that it produces an output voltage that stays the same regardless of changes in load, temperature or input voltage.

The ADR127AUJZ-R2 is used primarily in electronic devices that operate as power supplies, such as computers, medical equipment, communications systems, and consumer electronics. It is particularly suited for situations in which very precise voltage control is required, such as when the voltage being regulated must be completely accurate or is subject to change due to environmental or system conditions.

One of the main reasons why the ADR127AUJZ-R2 is so popular is that it offers a unique combination of features. It is capable of very precise voltage regulation, and it is also compact, lightweight, and consumes low power. Additionally, it is drop-in compatible with existing components, meaning that it can be easily integrated into existing systems and offers a practical solution for designers and manufacturers.

Another major advantage of the ADR127AUJZ-R2 is that it is designed for robustness and reliability. It is equipped with built-in protection features such as overvoltage protection and thermal shutdown, making it well-suited for demanding environments and industrial applications. Its low power consumption can help to reduce energy costs, making it beneficial for any system that requires voltage regulation.

The ADR127AUJZ-R2 provides precise voltage regulation and is based on the voltage regulation principle of series regulation. In series regulation, the output voltage is maintained by connecting a series shunt regulator between the input and the output of the system. The series shunt regulator reduces the voltage by a fixed amount and feeds the difference back to the input, thus ensuring that the output voltage stays constant despite changes in load, temperature or input voltage.

The ADR127AUJZ-R2 is designed to operate from a single supply and uses an adjustable output voltage range from 0.8 V to 60 V. This can be adjusted by connecting either an adjustable external reference voltage or an external resistor divider to the circuit. It also features an internal current source which can be used for various applications. The current source can be used for monitoring the output voltage, providing line sensing, or shuttering.

The ADR127AUJZ-R2 also features a number of protection features, such as over-current protection, over-temperature protection and ESD protection. These features ensure that the circuit is protected against both sudden current surges as well as long-term environmental stresses.

In conclusion, the ADR127AUJZ-R2 is a well-suited device for precise voltage regulation applications. Its combination of features make it beneficial for many different electronic devices and applications. It is a very efficient, low-power device and provides robust protection against environmental stresses and sudden current surges.
