LM4040C30IDBZTG4

Overview

The LM4040C30IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 100ppm/°C. It supports a maximum shunt current of 15mA and requires a minimum operating current of 82µA. Packaged in a surface-mount SOT-23-3 case, it is designed for low-power applications requiring stable voltage regulation.

Feature Summary

Provides a fixed 3V reference output with high precision
Operates over an extended industrial temperature range
Designed for low quiescent current consumption

Applications

Portable battery-powered instrumentation
Data acquisition systems
Microcontroller supply monitoring

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per official documentation. Confirm package marking codes match the SOT-23-3 footprint. Ensure design-in compatibility with existing thermal management strategies given the small form factor. Cross-reference datasheet revisions for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when a stable 3V reference is required in space-constrained designs. The ±0.5% accuracy suits general-purpose precision applications. Consider the 100ppm/°C temperature coefficient for environments with significant thermal variation. Verify that the 82µA minimum current requirement fits within the system's power budget constraints during idle states.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. It shares the same core architecture as other variants but is specifically configured for a 3V output. The family is known for replacing Zener diodes in low-cost, low-power applications where better stability and lower noise are required.
