REF3025AIDBZR

Overview

The REF3025AIDBZR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of ±0.2%. It operates within an input voltage range of 2.55 V to 5.5 V and supports a maximum shunt current of 25 mA. The device features a temperature coefficient of 75 ppm/°C and draws a maximum supply current of 50 µA. Housed in a compact SOT-23-3 package, it functions reliably across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

Provides stable reference voltage without requiring external load capacitors for stability
Operates with minimal headroom, functioning at supply voltages within 1 mV of the output
Suitable for intrinsic safety applications due to low power consumption

Applications

Loop-powered industrial sensors
Temperature and pressure transmitters
Portable measurement instruments

Procurement Notes

Verify the specific suffix 'DBZR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 75 ppm/°C temperature coefficient meets the thermal stability requirements of the target application environment. Ensure the 25 mA output current capability aligns with the load demands of the connected circuitry.

Selection Notes

Select this component when a fixed 2.5 V reference is needed with moderate precision and low quiescent current. It is appropriate for designs where space is limited by the SOT-23-3 footprint. Consider alternatives if higher accuracy or lower temperature drift is required for high-resolution data acquisition systems.

Part Context

This part belongs to the REF30xx family of low-power voltage references designed for industrial and portable applications. The series emphasizes low static current and high precision in small packages, making it suitable for battery-operated devices and loop-powered instrumentation where power efficiency is critical.
