REF2930AIDBZTG4

Overview

The REF2930AIDBZTG4 is a precision series voltage reference manufactured by Texas Instruments, providing a fixed 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. It consumes a typical supply current of 42 µA, with a maximum of 50 µA. The component functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Delivers a stable 3 V reference output with high thermal stability
• Operates efficiently with ultra-low quiescent current consumption
• Supports significant load currents for driving external circuits
• Designed for reliable performance across wide industrial temperature ranges

Applications

• Portable battery-powered instrumentation systems
• Data acquisition and measurement devices
• Industrial process control loops
• Medical equipment requiring precise signal conditioning

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead time requirements. Confirm that the SOT-23-3 package matches your PCB footprint constraints. Ensure the 2% initial accuracy meets your system tolerance specifications before finalizing procurement decisions.

Selection Notes

Select this component when a 3 V reference is required with moderate accuracy and low power consumption. The 25 mA output capability allows direct driving of ADCs or sensors without additional buffering. Consider the 100 ppm/°C drift if operating in environments with significant thermal fluctuations compared to lower-drift alternatives.

Part Context

This part belongs to the REF2930 series of precision voltage references from Texas Instruments. It shares the same core architecture and pinout as other variants in the family but is specifically configured for a 3 V output. The series is designed for applications requiring small form factors and low power operation in portable electronic devices.
