LM285Z-2.5#PBF

Overview

The LM285Z-2.5#PBF is a micropower voltage reference diode manufactured by Analog Devices Inc., utilizing a two-terminal band gap design. It provides a nominal output voltage of 2.5V with a guaranteed initial tolerance of ±1%. The device operates within a reverse current range of 20µA to 20mA and features a maximum dynamic impedance of 1Ω. It supports an operating temperature range from -40°C to +85°C and is housed in a 3-lead TO-92 plastic package.

Feature Summary

Guaranteed 1% initial voltage tolerance for precision applications
Micropower operation with low minimum operating current
Low dynamic impedance ensuring stable performance under varying load conditions

Applications

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

Procurement Notes

Verify the specific ordering suffix #PBF corresponds to lead-free packaging requirements when sourcing. Confirm that the Z package designation matches the required TO-92 form factor for your PCB layout. Ensure the component meets the specified -40°C to +85°C temperature range for your intended environment.

Selection Notes

Select this component when a fixed 2.5V reference with high initial accuracy is required. It is suitable for designs needing low power consumption and stable performance across a wide supply range. Consider the TO-92 package constraints for through-hole mounting versus surface-mount alternatives if space is limited.

Part Context

This part belongs to the LM185/LM285/LM385 family of micropower voltage references. The LM285 variant specifically covers the commercial temperature range, distinguishing it from the industrial LM185 and extended range LM385 models. The Z package indicates a standard plastic TO-92 housing commonly used in general-purpose electronics.
