LM4040C25ILPR

Overview

The LM4040C25ILPR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.048 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 100 ppm/°C. It requires a minimum cathode current of 80 µA and supports a maximum cathode current of 15 mA. The component is housed in a TO-92-3 through-hole package.

Feature Summary

Provides stable reference voltage with high initial accuracy
Operates at low micropower consumption levels
Designed for compact through-hole mounting applications

Applications

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

Procurement Notes

Verify the specific suffix ILPR corresponds to the TO-92-3 through-hole package configuration. Confirm the operating temperature range meets the application requirements of -40°C to +85°C. Ensure the circuit design accommodates the minimum cathode current of 80 µA for proper regulation. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a fixed 2.048 V reference is required in a through-hole format. The ±0.5% accuracy suits general precision applications. Consider the 100 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 15 mA maximum current capability against load requirements. Compare against SOT-23 variants if surface mount space is limited.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The C25 designation indicates the 2.048 V output variant. The ILPR suffix specifies the through-hole TO-92-3 packaging style, distinguishing it from surface-mount options like IDBZ or IM3.
