LM4040AIZ-3.0/NOPB

Overview

The LM4040AIZ-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3.0 V. It features an initial accuracy of ±0.1% and operates within a temperature range of -40°C to +85°C. The device utilizes a TO-92 through-hole package with three pins. Key electrical specifications include a maximum shunt current of 15 mA and a minimum operating current of 75 µA. It is designed for applications requiring high precision in compact form factors.

Feature Summary

Provides stable fixed voltage reference with high initial accuracy
Operates as a micropower shunt regulator with low current consumption
Suitable for through-hole mounting in standard TO-92 packages

Applications

Precision measurement systems
Portable instrumentation
Battery-powered equipment

Procurement Notes

Verify the specific suffix 'AIZ' corresponds to the desired accuracy grade and package variant. Confirm RoHS compliance status via the official datasheet. Ensure the supplier provides genuine Texas Instruments components to avoid counterfeit risks. Check for any recent product change notices affecting pinout or material composition.

Selection Notes

Select this component when a fixed 3.0 V reference is required with tight tolerance. The TO-92 package is appropriate for prototyping or low-volume through-hole designs. Consider thermal management if operating near maximum current limits. Compare against SOT-23 variants if board space is constrained.

Part Context

Part of the LM4040-N series, which offers various fixed voltage options and accuracy grades. The series is known for replacing Zener diodes in precision applications. The NOPB suffix indicates lead-free and rohs compliant manufacturing. This specific model targets cost-sensitive applications needing reliable voltage regulation.
