Overview
The REF3312AIDBZT is a precision series voltage reference from Texas Instruments, delivering a fixed output of 1.25 V with an initial accuracy of 0.15%. It operates within an input voltage range of 1.7 V to 5.5 V and draws a typical quiescent current of 3.9 uA. The device features a low temperature coefficient of 30 ppm/C and supports a maximum load current of 5 mA. It is housed in a compact SOT-23-3 surface-mount package and functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Provides high-precision fixed voltage output with tight initial accuracy tolerance
- Optimized for ultra-low power consumption suitable for battery-operated systems
- Maintains stable performance over wide operating temperature ranges
Applications
- Portable instrumentation requiring precise analog references
- Battery-powered measurement devices
- Data acquisition systems needing stable voltage sources
Procurement Notes
Verify the specific suffix 'DBZT' corresponds to the cut-tape or tray packaging variant as defined by Texas Instruments documentation. Confirm moisture sensitivity level handling requirements during assembly. Ensure the ordering part number matches the exact package and tape/reel specifications required for your manufacturing process to avoid compatibility issues.
Selection Notes
Select this component when a fixed 1.25 V reference with 0.15% accuracy is required in a small SOT-23-3 footprint. It is appropriate for designs prioritizing low quiescent current and high thermal stability. Compare against other REF33xx variants if different output voltages or package types are needed for space constraints.
Part Context
This part belongs to the REF3312 family of precision voltage references manufactured by Texas Instruments. The family includes various output voltages and package options such as SC70-3 and UQFN. The REF3312AIDBZT specifically utilizes the SOT-23-3 package, distinguishing it from other form factors in the same electrical specification group.
Replacement Considerations
REF3312AIDBZR offers identical electrical characteristics but differs in packaging format. REF3312AIRSET provides the same performance in an 8-UQFN package. Verify pinout compatibility and physical dimensions before substituting.
