Overview
The REF3330AIDBZT is a fixed-output series voltage reference from Texas Instruments, delivering a nominal 3 V output. It features an initial accuracy of ±0.15% and a temperature coefficient of 30 ppm/°C. The device operates within an input voltage range of 3.2 V to 5.5 V and draws a typical supply current of 3.9 µA. It supports a maximum load current of 5 mA and functions across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it is designed for precision analog applications requiring low power consumption.
Feature Summary
- Provides high-precision fixed voltage output with tight initial accuracy tolerance.
- Ensures stable performance over wide temperature variations with low drift characteristics.
- Optimized for battery-powered systems through ultra-low quiescent current consumption.
Applications
- Portable instrumentation and handheld measurement devices
- Data acquisition systems requiring precise analog references
- Battery-operated field transmitters and sensors
Procurement Notes
Verify the specific suffix 'DBZT' indicates cut-tape packaging when ordering samples or small quantities. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check lead times as they may vary based on production schedules and regional availability constraints.
Selection Notes
Select this component when a 3 V reference is required with superior temperature stability compared to standard bandgap references. Consider the SOT-23-3 package for space-constrained PCB layouts. Evaluate the 3.9 µA supply current against system power budgets for long-life battery applications. 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 micropower voltage references from Texas Instruments. The family includes various output voltages and packages, such as the SC-70 variant (REF3330AIDCKR). The REF3330 series is engineered for high-performance applications where size, power, and accuracy are critical design parameters.
Replacement Considerations
The REF3330AIDBZR is the reel-pack equivalent of this component. Other REF3330 variants with different output voltages or packages may serve as functional substitutes if electrical specifications align with the design requirements.
