LM4041DELT-1.2

Overview

The LM4041DELT-1.2 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed output voltage of 1.225 V. It features an initial accuracy of ±1% at 25 °C and a maximum temperature coefficient of 100 ppm/°C. The device operates within a current range of 60 µA to 12 mA and supports extended industrial temperatures from -40 °C to +125 °C. It is housed in the SOT-23-3 surface-mount package.

Feature Summary

Provides stable 1.225 V reference with high precision
Operates without external stabilizing capacitors
Maintains stability under capacitive loads
Suitable for space-constrained designs

Applications

Portable battery-powered equipment
Data acquisition systems
Handheld meters
Temperature measurement circuits

Procurement Notes

Verify the specific suffix 'D' indicates the 1% accuracy grade and 'ELT' denotes the SOT-23-3 tape-and-reel packaging configuration. Confirm the manufacturer is STMicroelectronics as specified, noting that other vendors may produce equivalent parts under different part numbers. Ensure the component meets the required extended temperature range specifications for the intended application environment.

Selection Notes

Select this component when a fixed 1.225 V reference is required with moderate precision (±1%) and low power consumption. It is appropriate for applications where saving board space is critical due to its small SOT-23-3 footprint. Consider the 100 ppm/°C temperature coefficient for thermal stability requirements across the -40 °C to +125 °C operating range.

Part Context

The LM4041 series consists of micropower shunt voltage references designed for precision applications. This specific model offers a fixed 1.225 V output, distinguishing it from adjustable variants. The series is known for eliminating the need for external capacitors while ensuring stability with various load conditions, making it a versatile choice for analog circuit design.
