LM4040BIM3X-3.0/NOPB

Overview

The LM4040BIM3X-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed output of 3V with an initial accuracy of ±0.2%. Packaged in a compact SOT-23-3 surface-mount format, 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 shunt current of 15 mA and requires a minimum operating current of 60 µA for stable regulation.

Feature Summary

Provides precise fixed voltage reference with high initial accuracy
Designed for low-power applications with micropower consumption
Compact three-terminal surface-mount package design

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring stable references
Microcontroller analog-to-digital converter inputs

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS standards during sourcing. Confirm the 'X' designation aligns with reel packaging requirements for automated assembly processes. Ensure the supplier provides valid manufacturer traceability documentation to guarantee component authenticity and quality control standards are met.

Selection Notes

Select this component when a 3V precision reference is required in space-constrained designs. It is suitable for circuits needing low quiescent current operation. Consider the 150 ppm/°C drift specification against thermal environment constraints. Evaluate the 15 mA maximum current capability against load requirements to ensure proper regulation margins.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It shares the same physical footprint and operational principles as other variants in the family, such as the 2.048V and 4.096V versions. The series is designed for general-purpose precision applications where size and power efficiency are critical factors.
