Overview
The REF3312AIRSER 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 features a maximum temperature coefficient of 30 ppm/°C and operates within an input voltage range of 1.7 V to 5.5 V. The device draws a typical supply current of 3.9 µA and supports a maximum load current of 5 mA. Housed in an 8-pin UQFN (1.5x1.5 mm) package, it functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low power consumption with typical supply current of 3.9 µA
- High precision performance with ±0.15% initial accuracy and 30 ppm/°C drift
- Compact footprint utilizing 1.5x1.5 mm UQFN-8 packaging
Applications
- Portable battery-powered instrumentation
- Data acquisition systems
- Industrial process control loops
Procurement Notes
Verify the specific suffix 'AIRSER' corresponds to the UQFN-8 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the manufacturer part number matches the exact electrical specifications required for your design.
Selection Notes
Select this component when a low-voltage operation down to 1.7 V is required alongside high precision. The UQFN-8 package offers space savings compared to traditional SOT-23 options while maintaining thermal stability. Consider the 3.9 µA quiescent current for strict power budget constraints in portable devices.
Part Context
This part belongs to the REF33xx family of low-power, high-precision voltage references. The family includes variants with different output voltages and packages, such as SC70-3 and SOT-23-3. The REF3312 specifically provides the 1.25 V output option optimized for applications requiring stable reference levels at low supply voltages.
Replacement Considerations
Check for REF3312AIRSR or REF3312AIRSG4 for alternative packaging or lead-free versions within the same series. Verify pinout compatibility if substituting with other 1.25 V references from different manufacturers.
