TEXAS INSTRUMENTS REF3030 Voltage Reference, 3V, SOT-23

The TEXAS INSTRUMENTS REF3030 is a precision, low-power voltage reference designed for demanding industrial applications, including temperature and pressure transmitters. It delivers excellent temperature drift and initial accuracy while consuming a typical quiescent current of only 42µA, making it exceptionally well-suited for loop-powered systems where power efficiency is critical. The device's low power consumption and high precision make it a reliable choice for pressure and temperature transmitter applications, and its stability without a load capacitor simplifies use in intrinsically safe and explosion-proof environments. The REF3030 operates over the extended industrial temperature range of -40°C to +125°C. It functions with supplies within 1mV of the output voltage under zero-load conditions, and its low dropout voltage, compact SOT-23 package, and low power consumption make it ideal for battery-powered devices. The device provides a fixed 3V output with an initial accuracy of 0.2% and a temperature coefficient of ±35ppm/°C, ensuring consistent performance across a wide range of conditions. It is a green product, free from antimony and bromine, and supports a high output current of 25mA.
