LM285Z-2.5#TRPBF

Overview

The LM285Z-2.5#TRPBF is a micropower voltage reference diode manufactured by Analog Devices Inc., utilizing the Z package (3-Lead Plastic TO-92). It provides a nominal reverse breakdown voltage of 2.5V with a guaranteed initial tolerance of 1%. The device operates within a temperature range of -40°C to +85°C and supports a minimum operating current of 20µA. Key electrical characteristics include a maximum dynamic impedance of 1Ω, an average temperature coefficient of 20ppm/°C, and wide band noise of 120µVrms.

Feature Summary

Two-terminal band gap reference design optimized for precision performance in micropower applications
Guaranteed low power consumption with operation at currents as low as 20µA
Advanced processing techniques ensure excellent stability over time and temperature variations

Applications

Portable meter references
Battery-operated systems
Panel meters
Current loop instrumentation

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format specified in the official documentation. Confirm the component is sourced from authorized channels to ensure authenticity. Cross-reference the manufacturer part number with the latest datasheet to validate the specific package type and electrical tolerances before procurement.

Selection Notes

Select this component when a stable 2.5V reference is required for battery-powered or portable devices where low quiescent current is critical. The 1% initial tolerance and 20ppm/°C temperature coefficient make it suitable for general-purpose instrumentation. Ensure the application current remains above the minimum operating threshold of 20µA for proper regulation.

Part Context

This component belongs to the LM185/LM285/LM385 family of micropower voltage references. The LM285 variant specifically covers the commercial temperature range (-40°C to +85°C), distinguishing it from the industrial LM185 and extended range LM385 options. The 'Z' designation indicates the TO-92 plastic package configuration.

Replacement Considerations

The LT1634 is listed as a related part offering higher accuracy (0.05%) and lower temperature drift (10ppm/°C). Consult the LT1634 datasheet for detailed substitution parameters if tighter specifications are required.
