Overview
The REF3318AIDBZR is a fixed series voltage reference from Texas Instruments, delivering a precise 1.8 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 1.7 V to 5.5 V and supports a maximum shunt current of 5 mA. It consumes only 3.9 uA of quiescent current, making it suitable for low-power applications. The component is housed in a compact SOT-23-3 package and functions reliably across an extended temperature range from -40 C to +125 C.
Feature Summary
- Provides stable 1.8 V reference with high initial accuracy
- Ultra-low power consumption for battery-operated systems
- Compact surface-mount packaging for space-constrained designs
Applications
- Portable instrumentation requiring precise voltage references
- Battery-powered measurement devices
- Data acquisition systems needing stable reference voltages
Procurement Notes
Verify the specific suffix 'DBZR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the humidity sensitivity level matches storage and handling protocols defined by the manufacturer's guidelines. Ensure the order quantity aligns with standard reel sizes to avoid cut-tape premiums or availability issues during procurement.
Selection Notes
Select this component when a fixed 1.8 V reference is required with tight tolerance specifications. Consider the 30 ppm/C drift rate for thermal stability requirements in the target environment. Evaluate the 3.9 uA supply current against total system power budgets. Verify that the SOT-23-3 footprint fits within the available PCB area constraints.
Part Context
This part belongs to the REF3318 family of precision voltage references designed for general-purpose applications. It complements other variants in the series offering different output voltages while maintaining similar performance characteristics. The device integrates into power management IC categories as a dedicated reference source for analog circuits.
Replacement Considerations
The REF3312AIDBZR serves as a parameter-equivalent alternative within the same product family, differing primarily in its fixed 1.25 V output voltage rather than the 1.8 V provided by the REF3318AIDBZR.
