LM236DG4-2-5

Overview

The LM236DG4-2-5 is a 2.5-V integrated reference circuit manufactured by Texas Instruments, functioning as a shunt voltage reference. It provides a fixed output voltage of 2.49 V with an initial accuracy of ±2%. The device operates within a temperature range of -25°C to +85°C and features a typical quiescent current of 400 µA. It supports a maximum output current of 10 mA and exhibits a typical temperature coefficient of 20 ppm/°C, with a maximum of 52 ppm/°C. The component is housed in an 8-SOIC package.

Feature Summary

• Provides a stable 2.5-V reference voltage suitable for precision applications
• Operates with low quiescent current consumption
• Available in surface-mount 8-SOIC packaging

Applications

• Portable instrumentation requiring stable voltage references
• Battery-powered systems needing low power consumption
• Data acquisition systems utilizing analog-to-digital converters

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status according to Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity. Check for any recent product change notices affecting specifications or assembly sites.

Selection Notes

Select this component when a fixed 2.5-V reference is required with moderate accuracy. Consider the 8-SOIC package for surface-mount assembly needs. Evaluate the temperature coefficient against environmental conditions. Compare quiescent current requirements with other available reference options. Verify compatibility with downstream circuitry input impedance.

Part Context

The LM236 series includes variants such as LM236-2.5 and LM236DR-2-5. The DG4 suffix typically denotes a specific tape and reel configuration or manufacturing revision. This part belongs to the broader family of bandgap voltage references designed for general-purpose use. Other packages include SOIC and DIP options within the same functional family.

Replacement Considerations

LM236DR-2-5 serves as a direct pin-compatible alternative within the same series. LM236DRE4-2-5 is also listed as an equivalent part number variant. Verify package dimensions and electrical specifications before substitution.
