Overview
The REF3030AIDBZRG4 is a fixed-output series voltage reference 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 exhibits a temperature coefficient of 75ppm/°C and functions across a junction temperature range of -40°C to +125°C. Packaged in a surface-mount SOT-23-3 case, it offers low noise performance with 33µVp-p (0.1Hz to 10Hz) and 94µVrms (10Hz to 1kHz).
Feature Summary
- Provides stable 3V reference with high precision.
- Ultra-low power consumption for battery applications.
- Compact three-pin surface mount package.
Applications
- Portable instrumentation systems
- Data acquisition modules
- Battery-powered measurement devices
Procurement Notes
Verify the G4 suffix indicates RoHS compliance and green material status as per manufacturer specifications. Confirm the SOT-23-3 package dimensions match PCB footprint requirements. Ensure operating conditions remain within the specified -40°C to +125°C thermal limits. Check for any specific handling precautions related to moisture sensitivity level 1.
Selection Notes
Select this component when a fixed 3V reference is required with tight initial tolerance. Consider the 75ppm/°C drift if wide temperature stability is critical. Compare against adjustable references if variable output is needed. Evaluate the 50µA quiescent current against system power budgets. Verify compatibility with the 3.05V minimum input voltage constraint.
Part Context
This part belongs to the REF30xx family of low-current, high-precision voltage references. It shares the same core architecture and pinout as the REF3030AIDBZR but includes the G4 suffix denoting lead-free and RoHS-compliant manufacturing. It serves as a direct replacement for non-G4 variants in existing designs requiring environmental compliance updates.
Replacement Considerations
The REF3030AIDBZR is the primary non-RoHS equivalent. Cross-reference with other 3V series references if pinout or accuracy requirements differ. Verify that substitute components maintain the 25mA load capability and similar noise characteristics.
