LM285DRG4-2-5

Overview

The LM285DRG4-2-5 is a micro-power shunt voltage reference from Texas Instruments, operating at a fixed output of 2.5V with an initial accuracy of ±1.5%. It features a temperature coefficient of 20 ppm/°C and supports a maximum shunt current of 20 mA. The device operates within a temperature range of -40°C to +85°C and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides stable micro-power voltage referencing for precision applications
• Utilizes shunt regulation architecture for circuit protection and reference stability
• Offers low temperature drift characteristics for consistent performance across thermal variations

Applications

• Portable battery-powered instrumentation systems
• Data acquisition and measurement circuits requiring stable references
• Power supply monitoring and control loops

Procurement Notes

Verify the RoHS compliance status and specific tape-and-reel packaging requirements before ordering. Confirm that the 8-SOIC footprint matches your PCB design constraints. Ensure the component meets the required operating temperature range for your specific environment. Check for any end-of-life notices or alternative sourcing options if long-term availability is critical.

Selection Notes

Select this component when a fixed 2.5V reference is needed in a surface-mount format. Consider the ±1.5% initial accuracy and 20 ppm/°C temperature coefficient against your system's precision requirements. Evaluate the 20 mA maximum shunt current capability to ensure it suits the load conditions. Compare against other LM285 variants if different voltages or packages are preferred.

Part Context

This part belongs to the LM285 series of micro-power shunt voltage references by Texas Instruments. It shares functional similarities with other members like the LM285DR-2-5 but includes the G4 suffix indicating lead-free/RoHS compliance. The series is designed for general-purpose voltage referencing in compact electronic designs.

Replacement Considerations

LM285DR-2-5 is a compatible alternative within the same family, though it may differ in packaging details or compliance markings.
