LM4040DIZ-3.0/NOPB

Overview

The LM4040DIZ-3.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, featuring a nominal output of 3.0 V with an initial accuracy of ±1%. It operates within a temperature range of -40°C to +85°C and utilizes a TO-92-3 package. The device supports a maximum cathode current of 15 mA and a minimum operating current of 62 µA. It exhibits a temperature coefficient of 150 ppm/°C and includes internal compensation for stability under capacitive loads.

Feature Summary

Provides stable precision voltage reference in a compact through-hole package
Capable of driving capacitive loads without external compensation components
Maintains low power consumption suitable for battery-operated systems

Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement devices
Data acquisition systems needing stable analog references

Procurement Notes

Verify the specific suffix 'D' indicates the ±1% accuracy grade and 'I' denotes the industrial temperature range (-40°C to +85°C). Confirm the 'NOPB' suffix ensures lead-free and RoHS compliance as per manufacturer specifications. Ensure the TO-92-3 package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a fixed 3.0 V reference with ±1% tolerance is required in a through-hole format. It is suitable for applications where moderate precision is sufficient and space constraints allow for larger packages compared to SOT-23 alternatives. Consider the 150 ppm/°C drift if high thermal stability is critical.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades (B, C, D) in both surface-mount and through-hole packages, providing designers with flexible options for precision reference needs across different form factors.
