Overview
The REF3330AIDBZTG4 is a precision series voltage reference from Texas Instruments, delivering a fixed 3 V output with an initial accuracy of ±0.15%. It operates within an input voltage range of 3.2 V to 5.5 V and supports a maximum load current of 5 mA. The device features a low temperature coefficient of 30 ppm/°C and consumes only 3.9 µA of supply current. It is housed in a compact SOT-23-3 package and functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Provides stable 3 V reference output with high initial accuracy
- Ultra-low power consumption suitable for battery-operated systems
- Compact surface-mount packaging for space-constrained designs
Applications
- Portable instrumentation requiring precise voltage standards
- Battery-powered measurement devices
- Data acquisition systems needing stable reference sources
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm compliance status and lifecycle stage. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Confirm that the component meets all necessary regulatory requirements for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when a fixed 3 V output is required with minimal quiescent current draw. The SOT-23-3 package offers a small footprint ideal for dense PCB layouts. Consider the 30 ppm/°C drift specification for applications operating across wide thermal ranges. Verify that the 5 mA output current capability meets the load requirements of the connected circuitry.
Part Context
This part belongs to the REF3330 family of precision voltage references manufactured by Texas Instruments. The family includes various output voltages and packages, sharing common architectural features for stability and low noise. The REF3330AIDBZTG4 specifically denotes the 3 V version in a SOT-23-3 package with green (RoHS-compliant) lead-free termination.
Replacement Considerations
The REF3330AIDBZR is a direct functional equivalent with identical electrical characteristics but may differ in packaging configuration or manufacturing lot specifications. Verify pinout compatibility and thermal performance when substituting.
