**REF02AZ/883C: A High-Precision, Military-Grade Voltage Reference IC**

In the realm of precision electronics, where system accuracy is non-negotiable, the voltage reference IC serves as the foundational anchor. The **REF02AZ/883C** stands out as a premier component in this category, engineered to deliver exceptional performance under the most demanding conditions. This device is not merely a standard voltage reference; it is a **military-grade component** certified to the stringent MIL-PRF-38535 Class H standard, ensuring utmost reliability for critical applications.

At its core, the REF02AZ/883C provides a **fixed +5.0V output** with remarkable accuracy. Its low initial error, typically within ±0.2%, is just the beginning. The IC exhibits an exceptionally **low temperature drift** of just 3ppm/°C (max) over the full military temperature range of -55°C to +125°C. This stability is paramount, as it ensures that the output voltage remains virtually unchanged despite extreme fluctuations in ambient temperature, a common scenario in aerospace, defense, and industrial environments.

Beyond temperature stability, the REF02AZ/883C is designed for long-term reliability. It features **low long-term stability**, meaning its output voltage will not drift significantly over thousands of hours of operation. This is complemented by excellent line and load regulation, minimizing variations caused by changes in input voltage or output current draw. The device can source up to 10mA and sink up to 2mA of output current, making it capable of driving multiple loads directly.

A key differentiator for the "/883C" suffix is its certification level. Components processed to this standard undergo **rigorous screening and testing**, including burn-in, temperature cycling, and constant acceleration, to eliminate early-life failures and guarantee performance in high-reliability systems. This makes the REF02AZ/883C the preferred choice for mission-critical applications such as **avionics systems, precision data acquisition, military radar, and automated test equipment (ATE)** where failure is not an option.

The IC operates from a wide input voltage range of +8V to +40V, adding to its flexibility in various system architectures. It also integrates a unique **trimmed 5kΩ precision resistor** accessible on the package, which can be used to adjust the output voltage slightly or for other circuit functions, eliminating the need for an external component.

**ICGOOODFIND:** The REF02AZ/883C is the epitome of precision and robustness. It transcends the role of a simple voltage regulator, establishing itself as a **high-reliability, system-critical component** trusted by designers who require guaranteed performance in extreme environments. Its military-grade certification, exceptional temperature stability, and proven longevity make it an indispensable solution for the world's most challenging electronic systems.
