AD587UQ is a voltage reference from ADI, part of the PMIC - Voltage Reference product family. It is suitable for a variety of applications such as digital control circuitry, data acquisition systems, and temperature sensing. This voltage reference device is a low-dropout linear voltage regulator that can provide very stable and accurate reference voltage with an overall temperature-coefficient error of ±1 ppm/°C maximum.

The AD587UQ offers a wide range of output voltage options, from 0.2V to 5.0V. It is capable of providing reference voltages with a current up to 25mA and a with relative accuracy of ±0.1%. The AD587UQ utilizes a low-dropout (LDO) linear voltage regulator that provides excellent temperature stability and low-noise operation. It also features a noise reduction technology which can minimize the noise level to assure only clean and stable power to the noise-sensitive applications.

The AD587UQ has several features that makes it particularly suitable for use in applications such as digital control circuitry and data acquisition systems. Its excellent DC accuracy and temperature stability make it ideal for use as a reference voltage for digital-to-analog converters and precision analog applications. Additionally, it offers very low output noise that make it perfectly suited for applications where very low-noise operation is desired.

The AD587UQ\'s low-dropout linear regulator design is based on a combination of bipolar/CMOS technology. The device comprises of an internal bandgap reference and an error amplifier, which control the output voltage of the device. In order to maintain accurate and stable output voltage, a feedback loop is implemented to monitor the reference voltage and output voltage and adjust its operation accordingly. The AD587UQ utilizes a dynamic tracking method to track the unloaded reference voltage and make sure it is stable and accurate under varying temperature and load conditions.

One of the most important features of the AD587UQ is its low power consumption. It has an operating current of only 2.2mA at 5V, allowing it to be powered from 5V or 3V supplies with no additional power delivery components required. It also has a shutdown mode, which significantly reduces the power consumption when in standby mode.

In summary, the AD587UQ is an ideal voltage reference solution for precision analog and digital applications, data acquisition systems, and temperature sensing. It combines low-noise operation, robust design, and low power consumption in a highly integrated package. It also allows for flexibility in applications by providing various output voltage options.
