Overview
The LM385DRG4-2-5 is a fixed shunt voltage reference IC manufactured by Texas Instruments, providing a nominal output of 2.5V with an initial accuracy of ±3%. It operates within a temperature range of 0°C to +70°C and features a maximum cathode current of 20mA. The device utilizes an 8-SOIC surface-mount package with dimensions of 4.9mm x 3.91mm x 1.58mm. Key electrical parameters include a load regulation of 20mV and a noise level of 120µVrms from 10Hz to 10kHz.
Feature Summary
- Provides stable 2.5V reference voltage for precision applications
- Micropower operation suitable for battery-powered systems
- Shunt topology allows simple circuit implementation
Applications
- Portable instrumentation reference sources
- Battery-operated measurement equipment
- Data acquisition system references
Procurement Notes
Verify the G4 suffix indicates lead-free composition and RoHS compliance when sourcing. Confirm the specific SOIC-8 package variant matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent product change notifications regarding manufacturing updates.
Selection Notes
Select this component when a fixed 2.5V reference is required in a compact surface-mount format. Consider the ±3% initial accuracy against application tolerance needs. Evaluate the 20mA maximum current capability for load requirements. Compare thermal performance within the 0°C to +70°C range against alternative packages.
Part Context
This part belongs to the LM385 family of adjustable micropower voltage references. The LM385 series offers various fixed and adjustable options in multiple packages. The DRG4 designation specifies the 8-SOIC package with lead-free construction. This family supports low-power design constraints across industrial applications.
Replacement Considerations
LM385DR-2-5 serves as a direct functional equivalent without the G4 suffix. LM385MX-2.5/NOPB provides a similar SOIC-8 package option. Verify pin compatibility and electrical specifications before substitution.
