LM4040BIM3-5.0/NOPB

Overview

The LM4040BIM3-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, delivering a fixed 5V output with ±0.2% initial accuracy. Housed in a compact SOT-23 surface-mount package, it operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 40 ppm/°C. The device supports a maximum shunt current of 15mA and exhibits a load regulation of 8mV. It is AEC-Q100 qualified for automotive applications.

Feature Summary

Provides stable fixed voltage reference with high precision
Operates efficiently at low quiescent currents
Designed for space-constrained surface-mount layouts

Applications

Portable battery-powered instrumentation
Automotive electronic control units
Data acquisition systems requiring precise analog references

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as per manufacturer specifications. Confirm the 'M3' designation aligns with the required SOT-23 pinout and marking codes. Ensure the 'B' grade matches the required ±0.2% accuracy tolerance for the target application circuit design.

Selection Notes

Select this component when a fixed 5V reference with tight initial accuracy is required in a small footprint. Consider the 40 ppm/°C temperature coefficient for thermal stability needs. Verify that the 15mA maximum shunt current capability meets the load requirements without exceeding power dissipation limits in the SOT-23 package.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed output voltages and accuracy grades. The LM4040BIM3 variant specifically targets applications needing high precision in a miniature three-terminal package, distinguishing it from standard or lower-accuracy counterparts in the broader family.
