LM4040C30QDBZT

Overview

The LM4040C30QDBZT 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 0.5%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 PPM/°C. It supports a maximum shunt current of 15 mA and requires a minimum operating current of 60 uA. The component is housed in a SOT-23-3 surface-mount package.

Feature Summary

Delivers stable 3 V reference voltage with 0.5% initial accuracy
Operates across extended industrial temperature range up to 125°C
Designed for low-power applications with micropower consumption

Applications

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

Procurement Notes

Verify the specific suffix QDBZT indicates automotive qualification and tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required temperature grade and accuracy specifications before procurement.

Selection Notes

Select this component when a 3 V reference is needed in a compact SOT-23-3 package. Consider the 150 PPM/°C temperature coefficient for thermal stability requirements. Verify that the 60 uA minimum current draw fits the system's quiescent power budget.

Part Context

This part belongs to the LM4040 family of precision shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The C30 variant specifically targets the 3 V output requirement.
