REF2930AIDBZRG4

Overview

The REF2930AIDBZRG4 is a fixed series voltage reference from Texas Instruments, providing a nominal output of 3 V. It features an initial accuracy of 2% and a temperature coefficient of 100 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 25 mA. Supply current is specified at a maximum of 50 µA, with typical operation around 42 µA. It functions reliably across a temperature range of -40°C to +125°C and is housed in a SOT-23-3 surface-mount package.

Feature Summary

• Provides a stable 3 V fixed output suitable for precision applications
• Operates with low supply current for energy-efficient designs
• Maintains performance across extended industrial temperature ranges

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition channels

Procurement Notes

Verify the component status before procurement as the source indicates this specific part number may be obsolete or subject to discontinuation by the manufacturer. Confirm availability through authorized distributors and check for valid replacement alternatives if production continuity is required for long-term projects.

Selection Notes

Select this component when a fixed 3 V reference is needed with moderate accuracy requirements. Consider the 2% initial tolerance and 100 ppm/°C drift against application needs. Ensure the SOT-23-3 package fits the design constraints and that the 25 mA load capability meets circuit demands.

Part Context

This part belongs to the REF2930 series of low-power voltage references from Texas Instruments. It shares the SOT-23-3 form factor with other members like the REF2933 and REF2950, offering different fixed output voltages while maintaining similar power consumption profiles and package dimensions for board space efficiency.
