REF3030AIDBZT

Overview

The REF3030AIDBZT is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 3V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 3.05V to 5.5V and draws a maximum supply current of 50µA. It features a temperature coefficient of 75ppm/°C and supports a maximum load current of 25mA. The component is housed in a SOT-23-3 surface-mount package and functions reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Delivers a stable 3V reference output with high initial accuracy
• Operates with low quiescent current for power efficiency
• Capable of sourcing up to 25mA load current
• Designed for reliable performance across extended industrial temperature ranges

Applications

• Providing reference voltages for analog-to-digital converters (ADCs)
• Serving as voltage references for digital-to-analog converters (DACs)
• Establishing precise thresholds in voltage comparator circuits
• Supporting sensor signal conditioning systems requiring stable bias

Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 75ppm/°C temperature coefficient meets the thermal stability requirements of the target application environment. Ensure the 3V output aligns with the system's reference voltage architecture before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 3V reference with ±0.2% initial accuracy is required. It is suitable for applications needing moderate drive capability up to 25mA. Consider the 75ppm/°C drift if operating in environments with significant temperature fluctuations. Compare against lower-drift variants like the REF3030E if tighter thermal stability is necessary for the design.

Part Context

This part belongs to the REF30xx family of precision bandgap voltage references from Texas Instruments. It shares the SOT-23-3 form factor with other members of the series, such as the REF3025 and REF3040, allowing for potential footprint compatibility across different reference voltage designs within the same product line.

Replacement Considerations

The REF3030AIDBZR is a compatible alternative offering identical electrical specifications but supplied in reel packaging instead of cut tape.
