REF3130AIDBZRG4

Overview

The REF3130AIDBZRG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 3.0 V with an initial accuracy of ±0.2%. It operates within an input voltage range of 3.05 V to 5.5 V and draws a maximum supply current of 100 µA. The device features a low temperature coefficient of 20 ppm/°C and supports a maximum load current of 10 mA. It functions reliably across an extended temperature range of -40°C to +125°C and utilizes a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides high-precision fixed voltage regulation with tight initial tolerance.
• Maintains stable performance over wide temperature variations.
• Designed for ultra-low power consumption in battery-operated systems.

Applications

• Portable instrumentation requiring precise analog references
• Battery-powered measurement devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing standards as defined by Texas Instruments. Confirm that the SOT-23-3 package matches your PCB footprint requirements. Ensure the fixed 3.0 V output aligns with your circuit design needs before procurement.

Selection Notes

Select this component when a fixed 3.0 V reference with ±0.2% accuracy is required. It is suitable for applications demanding low quiescent current and stability across industrial temperature ranges. Compare against other REF31xx variants if different output voltages or accuracies are needed.

Part Context

This part belongs to the REF31xx family of low-current, low-dropout voltage references. These components are designed for applications where space and power efficiency are critical constraints. The family offers various fixed output voltages while maintaining consistent performance characteristics and packaging options.

Replacement Considerations

The REF3130AIDBZR is the non-RoHS compliant equivalent. Other REF31xx series parts may serve as alternatives if different output voltages are acceptable.
