REF3020TB-GT3

Overview

The REF3020TB-GT3 is a high-precision CMOS voltage reference from the REF30xx family, providing a nominal output of 2.048 V with an accuracy of ±0.2%. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers up to 10 mA of sourced or sunk load current. The device features a maximum temperature drift of 50 ppm/°C over the -40°C to +85°C range and maintains low quiescent current at 30 µA max. Packaged in a space-saving SOT-23 (CASE 527AG) format, it typically requires no output bypass capacitor.

Feature Summary

• Provides stable voltage regulation with high accuracy and low temperature drift across industrial operating ranges
• Capable of sourcing or sinking up to 10 mA of load current without requiring an output bypass capacitor for most applications
• Operates efficiently with low quiescent current consumption while maintaining robust line and load regulation

Applications

• Battery powered systems
• A/D and D/A converters
• Precision regulator systems
• Portable medical equipment

Procurement Notes

Verify the specific suffix TB indicates the SOT-23 package configuration and GT3 denotes tape and reel shipping quantities. Confirm RoHS compliance and lead-free status as per manufacturer specifications. Ensure input voltage remains within the 2.7 V to 5.5 V operational limits during integration. Check for any recent obsolescence notices or lifecycle changes directly from onsemi documentation before finalizing procurement plans.

Selection Notes

Select this component when a precise 2.048 V reference is required with minimal external components. It is suitable for designs needing bidirectional current capability up to 10 mA. Consider the SOT-23 footprint for compact layouts. Verify that the 50 ppm/°C drift specification meets the thermal stability requirements of the target application environment.

Part Context

This part belongs to the REF30xx series of high-precision, low-drift CMOS voltage references manufactured by onsemi. The family includes various fixed output voltages such as 1.25 V, 2.5 V, 3.0 V, 3.3 V, and 4.096 V. All variants share similar electrical characteristics and packaging options, designed to simplify power management in precision analog circuits.

Replacement Considerations

Compatible substitutes within the same family include REF3012TB-GT3, REF3025TB-GT3, REF3030TB-GT3, REF3033TB-GT3, and REF3040TB-GT3. These parts offer identical performance profiles but provide different nominal output voltages. Ensure the alternative voltage level matches the system design requirements.
