LM385LPR-2-5

Overview

The LM385LPR-2-5 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 ±3%. The device operates within a temperature range of 0°C to +70°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 20 mA and a minimum operating current of 20 µA. The component is housed in a TO-92-3 package and is designed for through-hole mounting.

Feature Summary

Provides a stable 2.5 V reference voltage suitable for precision applications
Operates with micropower consumption, requiring a minimum current of 20 µA
Designed for through-hole integration using the TO-92-3 package

Applications

Portable battery-powered instrumentation
Data acquisition systems
Microprocessor supervisory circuits

Procurement Notes

Verify the specific suffix 'LPR' indicates tape-and-reel packaging when ordering. Confirm the temperature grade matches the design requirement of 0°C to +70°C. Ensure the ±3% accuracy tolerance is sufficient for the target application's precision needs before finalizing procurement.

Selection Notes

Select this component when a low-cost, through-hole voltage reference is required for general-purpose analog circuits. It is appropriate for designs where moderate accuracy (±3%) and standard temperature stability are acceptable. Consider alternative packages if surface-mount technology is preferred or if wider industrial temperature ranges are necessary.

Part Context

This part belongs to the LM385 family of two-terminal shunt voltage references from Texas Instruments. It serves as a cost-effective solution for establishing reference potentials in linear circuits. The device utilizes bandgap reference principles to maintain voltage stability across varying load and temperature conditions within its specified operational limits.
