LM4040D30ILP

Overview

The LM4040D30ILP is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum cathode current of 15 mA and requires a minimum operating current of 65 µA. The component is housed in a TO-92-3 through-hole package.

Feature Summary

• Provides a stable 3V reference voltage with high precision
• Designed for low power consumption applications
• Capable of handling up to 15mA load current

Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Temperature measurement circuits

Procurement Notes

Verify the specific suffix 'ILP' corresponds to the TO-92-3 through-hole package variant rather than surface-mount options. Confirm that the 'D' grade indicates the required ±1% accuracy tolerance for your design. Ensure the operating temperature range of -40°C to +85°C meets environmental requirements, as higher grades may be needed for extended ranges.

Selection Notes

Select this component when a fixed 3V reference is required in a through-hole configuration. The ±1% accuracy and 150 ppm/°C drift are suitable for general-purpose analog circuits. Consider the 65 µA minimum current requirement to ensure proper regulation during operation. Compare against other LM4040 variants if surface-mount packaging or tighter tolerances are necessary.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage outputs and accuracy grades. The 'D' suffix denotes the ±1% accuracy class, while '30' specifies the 3V output. The 'ILP' suffix identifies the TO-92-3 through-hole package style.

Replacement Considerations

LM4040D30ILPR (Reel version), LM4040D30ILP (Cut Tape version). Verify pinout compatibility before substitution.
