REF3020AIDBZRG4

Overview

The REF3020AIDBZRG4 is a precision CMOS voltage reference from the Texas Instruments REF30 series, housed in an SOT-23-3 package. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 50 ppm/°C. The device operates on a supply voltage range of 2.5 V to 5.5 V, drawing a typical quiescent current of 42 µA and a maximum of 50 µA. It supports a maximum load current of 25 mA and functions within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Delivers high precision with ±0.2% initial accuracy and low temperature drift for stable reference performance.
• Features ultra-low power consumption with a typical quiescent current of 42 µA, suitable for battery-operated systems.
• Operates without external load capacitors, simplifying circuit design and enhancing stability in compact form factors.

Applications

• Loop-powered industrial sensors
• Portable test and measurement equipment
• Medical instrumentation

Procurement Notes

Verify the suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the specific grade 'A' matches the required initial accuracy and temperature coefficient specifications for your application. Ensure the SOT-23-3 package orientation aligns with your PCB footprint design before finalizing procurement.

Selection Notes

Select this component when a fixed 2.048 V reference is required with tight tolerance and low power constraints. It is appropriate for applications needing stability across wide temperature ranges without external compensation components. Consider the 25 mA drive capability if driving moderate loads directly.

Part Context

This part belongs to the REF30xx family of precision voltage references designed for industrial and portable applications. The REF30 series is characterized by its CMOS architecture, which enables low power operation while maintaining high accuracy. The REF3020 variant specifically targets the 2.048 V output level, commonly used in data acquisition systems.

Replacement Considerations

REF3020AIDBZR is the non-RoHS compliant equivalent within the same package and specification profile.
