LM4040DIM3X-3.0/NOPB

Overview

The LM4040DIM3X-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3V with an initial accuracy of ±1%. It operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150 ppm/°C. The device supports a maximum cathode current of 15 mA and draws a minimum operating current of 62 µA. Packaged in a surface-mount SOT-23-3 (TO-236-3) case, it exhibits low noise characteristics, specified at 35 µVrms between 10 Hz and 10 kHz.

Feature Summary

Micropower operation with minimal quiescent current consumption
High precision voltage regulation with tight initial tolerance
Low noise performance suitable for sensitive analog circuits

Applications

Portable battery-powered instrumentation systems
Data acquisition and measurement equipment
Analog-to-digital converter reference sources

Procurement Notes

Verify the specific suffix 'DIM3X' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the 'NOPB' designation aligns with lead-free manufacturing standards and RoHS compliance requirements for your target market. Confirm that the 3V output variant matches the system design specifications before procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for stable voltage referencing in space-constrained designs. The ±1% accuracy offers a balance between cost and precision for general-purpose applications. Consider the 150 ppm/°C temperature coefficient against environmental operating conditions to ensure long-term stability meets system drift requirements.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references. The family provides various fixed voltage options in small packages like SOT-23 and TO-92. The LM4040 series is designed to replace larger Zener diodes, offering superior temperature stability and lower noise in a miniature footprint suitable for modern electronic assemblies.
