LM4040B25IDBZT

Overview

The LM4040B25IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA and a minimum operating current of 75 µA. Packaged in a surface-mount SOT-23-3 case, it exhibits a temperature coefficient of 150 ppm/°C.

Feature Summary

Provides stable 2.5 V reference voltage with high precision
Operates with low quiescent current for power efficiency
Designed for compact surface-mount applications

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring precise voltage references
Handheld meters and test equipment

Procurement Notes

Verify the specific suffix IDBZT corresponds to the SOT-23-3 package and commercial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration into production designs.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.2% accuracy is required in a small footprint. Ensure the application current remains within the 75 µA to 15 mA range to maintain regulation. Consider thermal management if operating near the upper temperature limit.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The B25 variant specifically denotes the 2.5 V output with 0.2% tolerance, while the DBZ suffix indicates the SOT-23-3 surface-mount packaging.
