REF3120AIDBZR

Overview

The REF3120AIDBZR is a series voltage reference IC manufactured by Texas Instruments, housed in an SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2.098 V to 5.5 V and draws a supply current of 135 µA. It features a temperature coefficient of 20 ppm/°C and supports a maximum load current of 10 mA. The component functions reliably across a wide operating temperature range from -40°C to +125°C.

Feature Summary

Provides a stable fixed output voltage suitable for precision analog circuits
Operates efficiently with low quiescent current consumption
Maintains high accuracy over a wide industrial temperature range

Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement systems
Data acquisition systems utilizing analog-to-digital converters

Procurement Notes

Verify the specific suffix 'DBZR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the thermal performance specifications align with the intended PCB layout and ambient operating conditions to ensure long-term reliability under continuous load.

Selection Notes

Select this component when a fixed 2.048 V reference is required with tight initial accuracy tolerances. Consider the low power consumption profile for battery-operated designs. Ensure the input voltage remains above the minimum dropout requirement while staying within the absolute maximum rating limits for safe operation.

Part Context

This part belongs to the REF31xx family of series voltage references from Texas Instruments. These devices are designed to offer improved performance over older generation references, providing better noise characteristics and stability in compact packages suitable for space-constrained electronic applications.
