LM4040DIM3X-2.5/NOPB

Overview

The LM4040DIM3X-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.5 V 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 typical quiescent current of 70 µA. Packaged in a compact SOT-23-3 surface-mount format, it delivers low noise performance of 35 µVrms (10Hz to 10kHz).

Feature Summary

Micropower operation with low quiescent current consumption suitable for battery-powered applications.
Compact SOT-23-3 surface-mount package design for space-constrained PCB layouts.
Low noise characteristics ensuring stable reference performance in sensitive analog circuits.

Applications

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

Procurement Notes

Verify the specific suffix 'DIM3X' against the official datasheet to confirm the tape-and-reel packaging configuration and ensure compatibility with automated assembly processes. Confirm that the ±1% accuracy class meets the system requirements, as other variants offer tighter tolerances. Check for RoHS compliance status indicated by the '/NOPB' designation.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a small SOT-23 package. Consider the ±1% initial accuracy and 150 ppm/°C temperature coefficient against stricter precision needs. Evaluate the 15 mA load capability and 70 µA standby current for power budget constraints compared to series reference alternatives.

Part Context

This part belongs to the LM4040-N family of precision micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The 'D' grade indicates ±1% initial accuracy, while the 'M3X' suffix denotes the SOT-23 package with reel packaging. This family is designed for general-purpose voltage referencing in industrial and consumer electronics.
