LM336LPRE3-2-5

Overview

The LM336LPRE3-2.5 is a two-terminal precision shunt voltage reference from Texas Instruments, providing a nominal output of 2.49 V. It operates within a temperature range of 0°C to 70°C and features an initial accuracy of ±4%. The device utilizes a TO-92 package with three pins for through-hole mounting. Key electrical specifications include a maximum shunt current of 10 mA, a minimum operating current of 600 µA, and a temperature coefficient of 20 ppm/°C. Input voltage requirements range from 2.44 V to 2.54 V.

Feature Summary

• Provides stable reference voltage via two-terminal shunt topology
• Ensures high precision with low initial accuracy tolerance
• Maintains consistent performance across specified industrial temperature ranges

Applications

• Precision analog-to-digital converter reference inputs
• Voltage regulation circuits requiring stable bias points
• Test and measurement equipment calibration references

Procurement Notes

Verify the exact suffix configuration against official datasheets to confirm lead-free status and specific binning options. Confirm package type matches design requirements. Check for RoHS compliance documentation. Ensure ordering codes align with manufacturer specifications to avoid functional mismatches.

Selection Notes

Select this component when a fixed 2.49 V reference is required in a through-hole package. Consider the ±4% initial accuracy and 20 ppm/°C temperature coefficient for circuit stability. Verify that the 10 mA maximum shunt current meets load requirements. Compare against other LM336 variants if different accuracies or packages are needed.

Part Context

Part of the LM336 series of two-terminal voltage references. This series offers various fixed voltage options and accuracy grades. The LM336LPRE3 variant specifically denotes the 2.49 V version in a TO-92 package with lead-free construction. It serves as a cost-effective solution for general-purpose precision applications.

Replacement Considerations

LM336Z-2.5/NOPB provides similar functionality in a TO-92 package. LM336M-2.5/NOPB offers the same voltage in an SOIC package. Verify pinout compatibility and thermal characteristics before substitution.
