The ADR125AUJZ-REEL7 is an advanced voltage reference for power management applications. It is a voltage reference regulator designed for use in automotive, industrial, commercial, and consumer applications. It is a suitable part for low power applications due to low power dissipation from adj turn-off resistors and circuit complexity reduction.

The ADR125AUJZ-REEL7 operates from a single 3V to 3.6V supply with a low quiescent current, making it an ideal device for battery powered applications. Its dual output configuration enables the user to create a single output with reference voltage tolerance up to ±0.02V, allowing for applications with very tight voltage regulation requirements. The output voltage can be programmed with a pair of simple external resistors, providing flexibility for different levels of voltage.

The ADR125AUJZ-REEL7 provides a load current limit of 75mA, and over temperature and over load protection, making it able to handle large transient loads without malfunctioning. The maximum output voltage noise is 7.0µVrms, reducing the impact of output voltage noise on sensitive systems. The ADR125AUJZ-REEL7 also has a maximum operating temperature of +125°C, which is well suited for harsh automotive and industrial environments.

At a block diagram level, the ADR125AUJZ-REEL7 features a bandgap reference for its voltage output, controlled by voltage feedback from a current sink. This allows for an accurate and stable reference voltage, with an accuracy of +/-0.02V over its operating temperature range. This is a great feature for applications where precision is critical, such as in industrial, medical and automotive applications.

In the voltage reference section, an internal reference voltage regulator is used, combined with an external driver circuit, to regulate the output voltage. This allows the user to control the voltage output, while at the same time maximizing its efficiency. The feedback loop is precisely mapped to ensure a stable output voltage. Additionally, over temperature and current protection make the ADR125AUJZ-REEL7 an ideal choice for applications with large transient loads.

The ADR125AUJZ-REEL7 is ideal for applications requiring low power consumption, high precision, and a wide operating temperature range. Its high accuracy ensures its compatibility with numerous applications. Furthermore, its overload protection and robustness makes it reliable for harsh industrial and automotive applications. The ADR125AUJZ-REEL7 can provide a reliable voltage reference with low power consumption, making it suitable for a variety of applications.
