LM4040DIZ-5.0/NOPB

Overview

The LM4040DIZ-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed output of 5V with an initial accuracy of ±1%. Packaged in a 3-pin TO-92 format, it operates within a temperature range of -40°C to +85°C. Key electrical characteristics include a maximum cathode current of 5mA, a minimum operating current of 100µA, and a temperature coefficient of 150ppm/°C.

Feature Summary

Provides stable reference voltage via shunt topology
Designed for low-power consumption applications
Suitable for space-constrained through-hole designs

Applications

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

Procurement Notes

Verify the specific suffix 'D' indicates the ±1% accuracy grade and 'IZ' denotes the TO-92 package configuration. Confirm that the 'NOPB' suffix ensures lead-free compliance and RoHS standards are met for your manufacturing requirements. Cross-reference the datasheet for thermal resistance values if high ambient temperatures are expected.

Selection Notes

Select this component when a fixed 5V reference is needed in a through-hole package with moderate precision. The 5mA maximum current limits its use in high-load scenarios compared to larger packages. Ensure the circuit design maintains the minimum 100µA cathode current to guarantee regulation stability across the specified temperature range.

Part Context

This device belongs to the LM4040 series of micropower shunt voltage references. It shares functional similarities with other members like the LM4040BIZ but differs in accuracy grade and package type. The series is widely used in general-purpose analog circuits where cost-effective, reliable voltage referencing is required without the complexity of adjustable regulators.
