LM285D-2.5R2G

Overview

The LM285D-2.5R2G is a fixed shunt voltage reference manufactured by onsemi, providing a stable 2.5V output. It operates within a current range of 20 µA to 30 mA and features an initial accuracy of ±1.5%. The device exhibits a temperature coefficient of 80 ppm/°C and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, it serves as a precision reference element for power management circuits requiring compact integration.

Feature Summary

• Provides a fixed 2.5V reference voltage with high stability
• Operates efficiently within a wide shunt current range
• Designed for surface-mount integration in compact layouts

Applications

• Precision analog-to-digital converter reference inputs
• Battery-powered instrumentation calibration
• Portable measurement equipment voltage regulation

Procurement Notes

Verify the specific suffix R2G against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Confirm RoHS compliance status through manufacturer documentation prior to procurement. Validate that the 2.5V fixed output aligns with circuit design requirements.

Selection Notes

Select this component when a fixed 2.5V reference is required in a small surface-mount package. Consider the 80 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 20 µA minimum current requirement against load conditions. Compare the ±1.5% initial accuracy against stricter tolerance applications where lower error margins are necessary.

Part Context

This part belongs to the LM285 series of shunt voltage references from onsemi. The series includes various fixed voltage options such as 1.2V and 2.5V variants. These components are designed for general-purpose voltage referencing in industrial and consumer electronics. The LM285 family offers a balance of performance and cost-effectiveness for standard reference applications.

Replacement Considerations

Check for LM285D-2.5G or LM285D-2.5R2G equivalents with identical pinouts. Verify functional compatibility with other 2.5V shunt references from different manufacturers. Ensure package dimensions match the 8-SOIC form factor for direct replacement.
