TPR31

Low-Noise, Low-Drift, Precision Voltage Reference

Overview

The TPR31 seires is a family of high-precision and low-temperature-drift voltage references with the initial accuracy of 0.05% and the maximum temperature coefficient of 10 ppm/°C. All products of the TPR31 series are able to support both sinking and souring current of ±10 mA and have a low dropout voltage.

The high precision and excellent temperature stability performance make the TPR31 series an ideal reference in the system with high resolution requirement.

The TPR31 series provides a SOT23-5 package with a wide range of output voltages. All the products are qualified to operate with the temperature range from –40°C to +125°C.
