LM4040C10ILP

Overview

The LM4040C10ILP is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.5%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a free-air temperature range of -40°C to +85°C. It requires a minimum cathode current of 45μA (typical) and supports a maximum continuous cathode current of 15mA. The component is housed in a TO-92 package.

Feature Summary

• Provides stable reference voltage with low dynamic impedance and low noise characteristics
• Operates without external capacitors and remains stable with all capacitive loads
• Utilizes fuse and Zener-zap reverse breakdown voltage trim for precise output tolerances

Applications

• Data-Acquisition Systems
• Energy Infrastructure
• Analog Input Modules
• Field Transmitters
• Precision Audio

Procurement Notes

Verify the specific suffix 'ILP' corresponds to the TO-92 package and industrial temperature grade (-40°C to 85°C). Confirm that the C-grade designation matches the required ±0.5% initial accuracy and 100ppm/°C temperature coefficient specifications for your design. Ensure the 10V output variant aligns with system requirements.

Selection Notes

Select this component when a fixed 10V reference is needed in a through-hole TO-92 package. It is suitable for applications requiring micropower operation with a minimum current draw of 45μA. Consider the C-grade performance if tighter tolerances like A or B grades are not necessary, balancing cost against the ±0.5% accuracy requirement.
