LM336B-2.5

Overview

The LM336B-2.5 is a precision shunt voltage reference integrated circuit manufactured by TAEJIN Technology Co., Ltd. It provides a fixed output voltage of 2.49V with an initial tolerance of ±1% or ±2%. The device operates in a TO-92-3 through-hole package and supports a maximum output current of 10 mA. It functions as a low-temperature coefficient reference, suitable for applications requiring stable voltage regulation within a standard operating temperature range.

Feature Summary

• Provides a fixed 2.49V reference output via shunt regulation topology
• Ensures high precision with tight initial tolerance specifications
• Utilizes a compact three-pin TO-92 through-hole package for easy integration

Applications

• General purpose voltage reference circuits
• Portable battery-powered equipment
• Data acquisition systems

Procurement Notes

Verify the manufacturer designation as TAEJIN Technology Co., Ltd. to distinguish from Texas Instruments variants. Confirm the specific tolerance grade (±1% vs ±2%) required for the application. Ensure the TO-92-3 package type matches the PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 2.49V shunt reference is needed in a small through-hole package. Consider the 10 mA current limit for load requirements. Compare initial accuracy grades against budget constraints. Verify thermal performance within the specified operating temperature range for the intended environment.

Part Context

This part belongs to the LM336 series of precision shunt voltage references. It serves as a cost-effective alternative to more complex regulator designs. The series is widely used in industrial and consumer electronics where stable voltage levels are critical for analog signal processing and measurement accuracy.

Replacement Considerations

LM336Z-5.0/NOPB is a related Texas Instruments variant but offers a different voltage level. Direct substitutes may include other LM336 family members with matching voltage and package constraints. Verify pinout compatibility before substitution.
