LM336BTA-2.5

Overview

The LM336BTA-2.5 is a precision shunt voltage reference integrated circuit manufactured by TAEJIN Technology. It functions as a fixed 2.49V reference diode with an initial accuracy of ±2%. The device operates within a maximum shunt current of 10 mA and features a temperature coefficient of 20 PPM/°C. Designed for through-hole mounting, it utilizes a TO-92-3 package. The component supports operation across a temperature range from 0°C to +70°C.

Feature Summary

• Provides stable 2.5V reference output via shunt regulation
• Low dynamic impedance characteristics for noise reduction
• Compact three-terminal TO-92 surface or through-hole form factor

Applications

• Precision voltage reference sources in measurement circuits
• Battery-powered instrumentation requiring stable bias voltages
• Temperature-compensated oscillator references

Procurement Notes

Verify the manufacturer designation on the datasheet, as TAEJIN produces this part while Texas Instruments manufactures similar LM336 variants. Confirm the specific suffix 'BTA' indicates the required tolerance and package type. Ensure the operating temperature range meets your environmental constraints. Cross-reference pinouts if substituting from other manufacturers. Validate RoHS compliance status for your region.

Selection Notes

Select this component when a fixed 2.5V reference is required with moderate accuracy. The TO-92 package suits low-volume or prototyping applications. Consider the 20 PPM/C temperature coefficient for thermal stability needs. Compare against LM336Z-2.5 if higher accuracy or different packaging is needed. Ensure the load current remains within the 10 mA limit.

Part Context

This part belongs to the LM336 family of precision shunt regulators. It shares functional similarities with the LM236 and standard LM336 series but offers specific tolerance grades. The BTA suffix typically denotes the TO-92 package variant produced by TAEJIN. It serves as a cost-effective alternative to bandgap references in simple linear regulator designs.

Replacement Considerations

LM336Z-2.5/NOPB (Texas Instruments) offers equivalent electrical performance in a TO-92 package. LM236-2.5 provides similar functionality with potentially different temperature ranges. Verify pin compatibility before substitution.
