REF3033AIDBZTG4

Overview

The REF3033AIDBZTG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 3.3V in a compact SOT-23-3 package. It features an initial accuracy of 0.2% and a maximum temperature coefficient of 50ppm/°C. The device operates with a low supply current of 50µA and supports a maximum input voltage of 5.5V. It provides a short-circuit current capability of 25mA and functions reliably within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

Provides high precision with 0.2% initial accuracy and low temperature drift for stable reference performance.
Features ultra-low power consumption with a typical supply current of 50µA suitable for battery-operated systems.
Capable of sourcing up to 25mA of load current without requiring external compensation capacitors.

Applications

Portable instrumentation and handheld devices
Industrial process control and loop-powered transmitters
Data acquisition systems requiring precise analog references

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 dimensions match your PCB footprint constraints. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain guaranteed accuracy specifications.

Selection Notes

Select this component when a fixed 3.2934V nominal output is required with tight tolerance. It is appropriate for designs prioritizing low quiescent current over ultra-high precision. Consider alternative packages if higher thermal dissipation or different pinout configurations are necessary for the specific application layout.

Part Context

This part belongs to the REF30xx family of CMOS voltage references designed for low-power applications. It utilizes bandgap technology to achieve stability across wide temperature variations. The device is intended as a direct replacement for older generation references in space-constrained portable electronics and industrial sensors.
