TL431KLP-BP

Overview

The TL431KLP-BP is a programmable precision shunt voltage reference integrated circuit manufactured by Micro Commercial Components (MCC). It operates within a cathode current range of 1 mA to 100 mA and supports output voltages adjustable up to 36 V. The device features effective temperature compensation across its operating range, ensuring stable performance. Packaged in a TO-92 through-hole housing, it serves as a reliable voltage reference solution for power management applications requiring precise regulation.

Feature Summary

• Programmable output voltage capability
• Effective temperature compensation
• Through-hole TO-92 packaging

Applications

• Power supply voltage references
• Linear regulator circuits
• Battery chargers

Procurement Notes

Verify the specific suffix 'BP' against the manufacturer's official datasheet to confirm package type and availability status. Cross-reference with MCC documentation to ensure the component matches required electrical specifications and thermal characteristics before procurement.

Selection Notes

Select this component when a low-cost, through-hole programmable shunt regulator is required. Ensure the application demands an output voltage adjustable up to 36V and can accommodate the 1 mA to 100 mA cathode current range. Verify that the TO-92 package fits the board layout constraints.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. It functions similarly to Zener diodes but offers superior accuracy and adjustability. The TL431 series is widely used in feedback loops for switching and linear power supplies due to its stability and precision.

Replacement Considerations

Check for direct substitutes such as TL431AIDBZR or equivalent shunt regulators from other manufacturers. Ensure pinout compatibility and matching electrical parameters like reference voltage tolerance and operating current range.
