LM4040D30QDBZRG4

Overview

The LM4040D30QDBZRG4 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. The component supports a maximum cathode current of 15 mA and draws a minimum operating current of 65 µA.

Feature Summary

Provides stable 3 V reference voltage with ±1% initial accuracy
Operates across extended industrial temperature range up to +125°C
Designed for low power consumption with micropower shunt architecture

Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement systems
Data acquisition circuits

Procurement Notes

Verify the complete part number including the Q suffix, which indicates automotive qualification requirements. Confirm the DBZR suffix corresponds to the specific SOT-23 tape and reel packaging configuration. Ensure compatibility with RoHS3 standards and check for any specific handling instructions related to moisture sensitivity level 1 classification during assembly processes.

Selection Notes

Select this component when a 3 V reference with ±1% tolerance is required for automotive or high-temperature applications. The SOT-23-3 package offers space efficiency for compact designs. Consider the 150 ppm/°C temperature coefficient for thermal stability needs. Verify that the 65 µA minimum current draw fits within the system's quiescent power budget constraints.

Part Context

This device belongs to the LM4040 family of precision micropower shunt voltage references from Texas Instruments. The family includes various output voltages and accuracy grades. The 'D' grade denotes ±1% initial accuracy, while the 'Q' suffix signifies automotive qualification. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing.
