REF3230AIDBVR

Overview

The REF3230AIDBVR is a fixed series voltage reference IC manufactured by Texas Instruments, housed in an SOT-23-6 surface-mount package. It provides a stable 3V output with a tight initial tolerance of ±0.2%. The device operates within an input voltage range of 3.05V to 5.5V and supports a maximum output current of 10 mA while consuming only 135 µA of supply current. It features a temperature coefficient of 20 ppm/°C over an operating temperature range of -40°C to 125°C. Noise performance is specified at 39 µVp-p from 0.1Hz to 10Hz and 57 µVrms from 10Hz to 10kHz.

Feature Summary

• Fixed 3V series voltage reference output
• High precision ±0.2% initial accuracy
• Low power consumption with 135µA supply current
• Wide industrial temperature operation range

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Portable instrumentation powered by single supplies
• Calibration equipment needing low-drift references

Procurement Notes

Verify component authenticity through authorized channels due to the presence of alternative part numbers such as REF3230AIDBVRG4. Confirm that the SOT-23-6 package matches design requirements. Check for RoHS3 compliance status if environmental regulations apply. Ensure the NRND status does not conflict with long-term production plans. Validate datasheet revisions against current manufacturing specifications before integration.

Selection Notes

Select this component when a fixed 3V reference is required with high initial accuracy and low noise. Consider the SOT-23-6 package for space-constrained PCB layouts. Evaluate the 20 ppm/°C temperature coefficient against thermal environment constraints. Compare supply current requirements with battery life expectations. Verify input voltage compatibility within the 3.05V to 5.5V range for system power rails.

Part Context

This part belongs to the REF3230 family of voltage references from Texas Instruments. It shares architectural similarities with other members like REF3212, REF3225, and REF3330, differing primarily in output voltage. The DBVR suffix indicates the specific SOT-23-6 tape-and-reel packaging variant. It is designed for applications demanding stability without external trimming components.

Replacement Considerations

REF3230AIDBVT serves as a compatible alternative with identical electrical characteristics but potentially different packaging options.
