Description and Introduction

Precision Micropower, Low Dropout, Voltage References **Introducing the REF191FS Precision Voltage Reference**  

In the realm of precision electronics, stable and accurate voltage references are essential for ensuring reliable performance in critical applications. The REF191FS stands out as a high-performance, low-power voltage reference, delivering exceptional accuracy and thermal stability for demanding designs.  

Engineered for precision, the REF191FS provides a fixed 1.25V output with an initial accuracy of ±0.1%, making it ideal for data acquisition systems, industrial instrumentation, and medical devices. Its low temperature coefficient of 15ppm/°C ensures minimal drift over a wide operating range, maintaining consistency even in fluctuating environments.  

With an ultra-low noise output of 4µVp-p, the REF191FS minimizes signal interference, enhancing the integrity of sensitive analog circuits. Its low quiescent current of 50µA makes it suitable for battery-powered applications where power efficiency is paramount. Additionally, the device operates over a wide supply range of 2.7V to 5.5V, offering flexibility in various system configurations.  

Housed in a compact SOT-23 package, the REF191FS combines precision with space-saving design, making it an excellent choice for modern, high-density PCB layouts. Its robust performance and reliability make it a preferred solution for engineers seeking a dependable voltage reference without compromising on efficiency or accuracy.  

For applications requiring unwavering precision and stability, the REF191FS sets a benchmark in voltage reference technology, ensuring consistent performance in even the most demanding environments.
