The REF2930 from Texas Instruments is a high-precision, low-power, low-dropout voltage reference. This device is part of a family of products that are designed to provide a stable and accurate reference voltage for various applications, including data converters, portable instrumentation, and battery-powered devices.

Featuring a typical initial accuracy of 0.2% and a guaranteed accuracy of ±0.5% over the entire temperature range from -40°C to +125°C, the REF2930 is an ideal choice for precision applications. The low dropout voltage of just 17mV at a 1mA load allows this voltage reference to function correctly even when the supply voltage is very close to the output voltage, which is particularly useful in battery-operated equipment.

With a low supply current of 50μA (typical), which minimizes power consumption, the REF2930 is optimized for energy-sensitive applications. Moreover, the device features a low temperature coefficient of 50ppm/°C (max), ensuring a consistent performance across a wide range of operating conditions.

The REF2930 is available in a small SOT-23 package, making it suitable for space-constrained applications. It offers a fixed 3.0V output, which can be an ideal voltage reference for 3.3V systems, providing a margin for system error and ensuring reliable operation under all conditions.
