LM4040D30IDBZR

Overview

The LM4040D30IDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3 V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 PPM/°C. It is housed in a surface-mount SOT-23-3 package. Electrical characteristics include a maximum shunt current of 15 mA and a minimum operating current of 65 µA.

Feature Summary

Provides stable fixed reference voltage for precision applications
Operates over extended industrial temperature range
Designed for low power consumption in portable systems

Applications

Portable instrumentation circuits
Battery-powered measurement devices
Data acquisition systems requiring stable references

Procurement Notes

Verify the specific suffix IDBZR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the D-grade accuracy meets the system tolerance requirements. Ensure thermal management aligns with the specified operating temperature limits during high-current operation.

Selection Notes

Select this component when a 3 V reference is needed with ±1% accuracy and wide temperature stability. Compare against higher accuracy grades if tighter tolerances are required. Consider the SOT-23-3 footprint constraints and verify compatibility with existing PCB layouts and soldering profiles.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage options and accuracy grades. The LM4040D variant specifically denotes the standard accuracy tier suitable for general-purpose precision applications where cost and size are critical factors.
