Overview
The REF3112AIDBZT is a precision series voltage reference from Texas Instruments, delivering a fixed output of 1.25 V. It features an initial accuracy of 0.2% and a temperature coefficient of 20 ppm/°C. The device operates within an input voltage range up to 5.5 V and draws a typical supply current of 100 µA. It supports a maximum shunt current of 10 mA and functions reliably across a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount format, it is designed for low-power applications.
Feature Summary
- Provides stable 1.25 V reference with high initial accuracy
- Low power consumption suitable for battery-operated systems
- Operates stably under capacitive loads without external compensation
Applications
- Portable battery-powered equipment
- Data acquisition systems
- Medical devices
- Handheld test instruments
Procurement Notes
Verify the specific suffix 'DBZT' corresponds to the SOT-23-3 package and tape-and-reel or cut-tape availability as required by your assembly process. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage constraints are respected to maintain specified performance levels.
Selection Notes
Select this component when a fixed 1.25 V reference with 0.2% accuracy and 20 ppm/°C drift is required in a small SOT-23-3 footprint. It is appropriate for designs prioritizing low quiescent current (100 µA) and stability under capacitive loads. Compare against REF3312 for lower current needs or REF2912 for relaxed accuracy requirements.
Part Context
Part of the REF31xx family of precision, low-power, low-dropout series voltage references. This series is engineered for portable and battery-supplied applications due to its small size and minimal current draw. The REF3112 specifically offers a 1.25 V output, complementing other variants like REF3120, REF3125, REF3130, REF3133, and REF3140 within the same lineup.
Replacement Considerations
REF3112AIDBZR shares identical electrical specifications but differs in packaging format (reel vs. cut tape). REF3312AIDCKTG4 offers similar voltage but lower current and different package. Verify pinout compatibility and thermal characteristics before substitution.
