Overview
The REF3312AIDCKR 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 µA. 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 SC70-3 surface-mount package and functions reliably across an extended industrial temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low power consumption suitable for battery-operated systems
- High precision with tight initial accuracy and low drift over temperature
- Compact footprint optimized for space-constrained designs
Applications
- Portable instrumentation requiring long battery life
- Data acquisition systems needing stable reference voltages
- Medical devices with strict power and accuracy constraints
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Confirm end-of-life status if sourcing from secondary markets. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.
Selection Notes
Select this component when a fixed 1.25 V reference is required with minimal power draw. Compare against other REF33xx variants if different output voltages or packages like SOT-23-3 are preferred. Verify that the 5 mA load capability meets circuit requirements.
Part Context
This part belongs to the REF33xx family of nanopower voltage references designed for high precision applications. The family offers multiple output voltages and package options including SC70-3, SOT-23-3, and UQFN-8 to accommodate various design constraints while maintaining consistent electrical performance characteristics.
Replacement Considerations
Check for direct pin-compatible substitutes within the same REF33xx series. Verify equivalent electrical parameters such as drift and quiescent current before substituting.
