LM4040D25ILPR

Overview

The LM4040D25ILPR is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 15 mA and requires a minimum cathode current of 75 µA for regulation. The component is housed in a TO-92-3 through-hole package, suitable for space-constrained applications requiring precision voltage referencing.

Feature Summary

Provides stable 2.5 V reference voltage with ±1% initial accuracy
Operates across extended industrial temperature range up to +125°C
Micropower design with low minimum operating current
Through-hole TO-92-3 package for easy integration

Applications

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

Procurement Notes

Verify the specific suffix ILPR indicates the TO-92-3 through-hole package variant. Confirm RoHS compliance status as detailed in official documentation. Check for end-of-life notices or obsolescence warnings from Texas Instruments before finalizing procurement decisions.

Selection Notes

Select this component when a through-hole voltage reference is required for 2.5 V applications. Ensure the circuit design accommodates the 15 mA maximum shunt current capability. Verify that the 150 ppm/°C temperature coefficient meets the system's thermal stability requirements across the intended operating temperature range.

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 D series denotes ±1% initial accuracy. The ILPR suffix specifies the TO-92-3 through-hole packaging option distinct from surface-mount variants.
