LM285Z-1.2G

Overview

The LM285Z-1.2G is a micropower shunt voltage reference diode manufactured by onsemi, housed in a 3-pin TO-92 through-hole package. It provides a fixed nominal output voltage of 1.235V with an initial accuracy of ±2%. The device operates within a wide current range from 10µA to 20mA, featuring low dynamic impedance and low noise characteristics. It is designed for stable operation over time and temperature, making it suitable for battery-powered applications requiring extended life.

Feature Summary

Micropower shunt regulation topology
Low dynamic impedance design
Wide operating current range capability

Applications

Portable instrumentation circuits
Battery-powered measurement devices
General-purpose analog circuit references

Procurement Notes

Verify the specific manufacturer lot and date code upon receipt, as component availability may vary across supply channels. Confirm that the received units match the exact LM285Z-1.2G designation to ensure compatibility with existing designs. Check for any obsolescence notices or lifecycle status updates from onsemi before finalizing procurement plans.

Selection Notes

Select this component when a low-cost, fixed 1.2V reference is required for low-current applications. Ensure the load current remains within the specified 10µA to 20mA range for optimal regulation. Consider the TO-92 package constraints for thermal management and board space compared to surface-mount alternatives.

Part Context

This part belongs to the LM285/LM385 family of micropower voltage references. These devices utilize bandgap technology to provide stable reference voltages. The LM285 variant typically offers a wider operating temperature range compared to commercial grade parts, suitable for broader industrial environments.
