REF3030AIDBZTG4

Overview

The REF3030AIDBZTG4 is a fixed series voltage reference IC from Texas Instruments, providing a nominal output of 3V. It features an initial accuracy of ±0.2% and operates within an input voltage range of 3.05V to 5.5V. The device draws a maximum supply current of 50µA and supports a maximum load current of 25mA. It is housed in a surface-mount SOT-23-3 package with dimensions of 3.04mm x 1.05mm. The unit functions reliably across a temperature range of -40°C to +125°C, exhibiting a temperature coefficient of 75ppm/°C and line regulation of 375µV/V.

Feature Summary

• Delivers stable 3V reference output with high precision for sensitive analog circuits
• Operates on ultra-low power consumption suitable for battery-powered systems
• Provides robust performance across extended industrial temperature ranges
• Utilizes compact surface-mount packaging for space-constrained designs

Applications

• Analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) voltage sources
• Portable instrumentation requiring low power operation
• Data acquisition systems needing precise voltage standards

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the package type matches the required PCB footprint. Ensure the operating environment stays within the specified thermal limits. Check for any recent product change notices regarding assembly sites or marking updates. Validate that the 3V output aligns with system requirements before integration.

Selection Notes

Select this component when a fixed 3V reference is required with ±0.2% initial accuracy. It is appropriate for applications demanding low quiescent current under 50µA. Consider this part for designs constrained by the SOT-23-3 form factor. Evaluate if the 75ppm/°C drift meets the system's long-term stability needs. Compare against higher precision alternatives if tighter tolerance is necessary.

Part Context

This device belongs to the REF30xx family of low-current, low-dropout voltage references. These components are designed for precision applications where size and power efficiency are critical. The family offers various fixed output voltages in a minimal 3-pin package. They serve as fundamental building blocks for signal conditioning chains in mixed-signal systems.

Replacement Considerations

REF3030AIDBZR is the non-RoHS compliant equivalent. REF3030AIDBZRG4 is an alternative designation for the same functional device. Verify pin compatibility and electrical specifications before substitution.
