LM236Z-2.5

Overview

The LM236Z-2.5 is a two-terminal integrated reference circuit manufactured by National Semiconductor, now part of Texas Instruments. It functions as a precision shunt voltage reference diode with a nominal output voltage of 2.49 V. The device operates within an industrial temperature range of -25°C to 85°C and features a maximum initial accuracy of 2%. It supports a maximum output current of 10 mA and maintains a typical quiescent current of 400 µA. The component utilizes an 8-pin SOIC package group.

Feature Summary

• Provides stable 2.5V reference voltage via two-terminal operation
• Integrated circuit design for compact implementation
• Suitable for industrial temperature environments

Applications

• Precision voltage regulation circuits
• Analog-to-digital converter references
• Battery-powered instrumentation

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package type and temperature rating. Confirm RoHS compliance status for modern manufacturing requirements. Cross-reference datasheet revisions to ensure pinout compatibility with existing designs.

Selection Notes

Select this component when a fixed 2.5V reference is required in an 8-pin surface-mount package. Consider the 2% initial accuracy and 52 ppm/°C temperature coefficient limits. Evaluate the 10 mA load capability against circuit demands. Compare against LM136 or LM336 variants if different packages or accuracies are needed.

Part Context

This device belongs to the LM236 family of integrated reference circuits. It serves as a direct replacement for discrete Zener diodes in many applications, offering superior stability and lower noise. The Z suffix typically denotes a specific plastic package variant within the broader LM236 product line.
