LM236D-2-5

Overview

The LM236D-2-5 is a 2.5-V integrated reference circuit manufactured by Texas Instruments, housed in an 8-SOIC package. It operates within a temperature range of -25°C to 85°C and features a typical quiescent current of 400 µA. The device provides a fixed output voltage of 2.49 V with an initial accuracy of ±2%. It supports a maximum output current of 10 mA and exhibits a typical temperature coefficient of 20 ppm/°C, ensuring stable performance for precision applications.

Feature Summary

• Provides a precise 2.5-V reference voltage with high initial accuracy
• Operates efficiently with low quiescent current consumption
• Designed for shunt regulation applications in compact surface-mount packages

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Battery-powered instrumentation circuits

Procurement Notes

Verify the specific suffix 'D' confirms the 8-SOIC package variant when ordering. Ensure the required operating temperature range aligns with the commercial grade (-25°C to 85°C). Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the manufacturer part number with distributor catalogs to ensure availability of the correct tape-and-reel or cut-tape quantity.

Selection Notes

Select this component when a stable 2.5-V reference is required in space-constrained designs. The 8-SOIC package facilitates automated surface-mount assembly. Consider the 400 µA quiescent current for battery life calculations. Verify that the 10 mA load capability meets the downstream circuit requirements without exceeding thermal limits.

Part Context

This device belongs to the LM236 family of integrated reference circuits, which are widely used as voltage references in data acquisition systems. The LM236 series offers improved performance over discrete zener diodes, providing better stability and lower noise. It serves as a cost-effective solution for general-purpose voltage referencing needs in industrial and consumer electronics.

Replacement Considerations

LM236DR-2-5: Identical electrical specifications and pinout; differs only in packaging format (tape-and-reel vs. tube). LM336-2.5: Similar functionality but may exhibit different temperature coefficients and current requirements; verify datasheet compatibility before substitution.
