LM4040C10ILPE3

Overview

The LM4040C10ILPE3 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

• Offers low dynamic impedance and low noise for stable performance across wide operating currents and temperatures
• Remains stable with all capacitive loads without requiring external output capacitors
• Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure tight output tolerances

Applications

• Data-acquisition systems
• Energy infrastructure monitoring
• Analog input modules
• Field transmitters
• Precision audio circuits

Procurement Notes

Verify the specific ordering suffix 'E3' corresponds to lead-free compliance requirements for your assembly process. Confirm that the TO-92 through-hole package aligns with your PCB footprint design. Ensure the industrial temperature range (-40°C to +85°C) meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when a 10V reference with ±0.5% accuracy is required in a through-hole configuration. The C-grade specification balances cost and performance for general-purpose applications. Consider the 45μA minimum operating current to ensure proper biasing in low-power designs.
