LM4040C30IDBZT

Overview

The LM4040C30IDBZT 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 +85°C and features a temperature coefficient of 100 ppm/°C. It supports a maximum shunt current of 15 mA and requires a minimum cathode current of 82 µA for regulation. Packaged in a surface-mount SOT-23-3 (SC-59) case, it is available in reel, cut tape, and Digi-Reel formats.

Feature Summary

Provides a stable 3V reference voltage with high initial accuracy
Operates efficiently at low micropower levels suitable for battery applications
Designed for surface-mount assembly in compact electronic circuits

Applications

Portable battery-powered instrumentation systems
Data acquisition and measurement equipment requiring precise references
Handheld devices and mobile electronics with space constraints

Procurement Notes

Verify the specific suffix IDBZT against official Texas Instruments documentation to confirm the SOT-23-3 package and commercial grade temperature rating. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental files before finalizing procurement decisions.

Selection Notes

Select this component when a 3V reference with ±0.5% accuracy is required in a small SOT-23-3 package. Consider the 100 ppm/°C temperature coefficient for thermal stability needs. Verify that the operating current requirements fall within the specified 82 µA minimum and 15 mA maximum limits for proper regulation and noise performance.

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 C30 designation indicates the 3V output variant with commercial grade specifications. The IDBZT suffix specifies the SOT-23-3 surface-mount package and tape-and-reel delivery method.
