LM285LPR-2-5

Overview

The LM285LPR-2-5 is a shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It operates within a temperature range of -40°C to +125°C and features a fixed output voltage of 2.5V with an initial accuracy of ±1.5%. The device utilizes a TO-92-3 package for through-hole mounting and supports a maximum shunt current of 20 mA. Its low dynamic impedance and noise characteristics make it suitable for microprocessor supervisory circuits and portable instrumentation.

Feature Summary

Provides a stable 2.5V reference voltage with high initial accuracy
Operates reliably across extended industrial temperature ranges
Features low dynamic impedance for consistent performance under varying load conditions

Applications

Microprocessor supervisory circuits
Portable instrumentation
Battery-powered systems

Procurement Notes

Verify the specific suffix 'LP' indicates the correct temperature grade and packaging configuration for your design requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal management and mechanical mounting constraints for the target application environment.

Selection Notes

Select this component when a fixed 2.5V reference is needed in a through-hole TO-92 package. Consider the ±1.5% initial accuracy and temperature coefficient specifications against circuit tolerance requirements. Evaluate the 20 mA maximum current capability to ensure adequate headroom for the reference biasing network in the final design.

Part Context

This part belongs to the LM285 family of shunt voltage references, which are widely used for providing precise voltage levels in analog and digital circuits. The LM285 series offers various voltage options and packages, serving as a fundamental building block for power management and signal conditioning applications where stability and accuracy are critical.
