LM4040C25ILP

Overview

The LM4040C25ILP is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150 ppm/°C. It utilizes a TO-92-3 through-hole package, supporting a maximum cathode current of 15 mA and a minimum operating current of 75 µA.

Feature Summary

Provides a stable 2.5 V reference voltage with high initial accuracy
Designed for low power consumption applications via micropower operation
Utilizes a compact three-pin through-hole package for easy integration

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring precise voltage references
Temperature measurement circuits

Procurement Notes

Verify the specific suffix ILP corresponds to the TO-92-3 through-hole package configuration. Confirm the C grade indicates ±0.5% accuracy and 150 ppm/°C temperature coefficient. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a through-hole design. The ±0.5% accuracy suits general-purpose precision applications. Consider the 150 ppm/°C temperature coefficient against environmental conditions. Compare with SOT-23 variants if board space constraints necessitate surface-mount technology instead of through-hole mounting.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The LM4040 series is designed to replace Zener diodes in many applications, offering better stability and lower noise characteristics while maintaining low power consumption suitable for battery-operated devices.
