TL431V-TP

Overview

The TL431V-TP is an adjustable precision shunt voltage regulator manufactured by Micro Commercial Components (MCC). It functions as a programmable reference source with an output voltage range adjustable up to 36 V. The device features a trapping current capability ranging from 1 mA to 100 mA and includes effective temperature compensation across its operating range. Packaged in SOT-23, it serves as a versatile component for power management applications requiring stable voltage references.

Feature Summary

• Adjustable output voltage capability extending up to 36 V
• Effective temperature compensation within the specified working range
• Trapping current capability supporting operation between 1 mA and 100 mA

Applications

• Precision voltage reference circuits
• Power supply feedback loops
• Battery charging control systems

Procurement Notes

Verify the specific suffix 'V' against the manufacturer's official documentation to confirm package type and electrical tolerances. Ensure compatibility with existing PCB footprints for the SOT-23 form factor. Cross-reference datasheet revisions to confirm compliance with current environmental standards such as RoHS before finalizing procurement specifications.

Selection Notes

Select this component when a compact, adjustable reference is required for low-power feedback applications. The SOT-23 package suits space-constrained designs. Verify that the required cathode current falls within the 1 mA to 100 mA operational window. Confirm thermal requirements align with the device's compensation characteristics for the intended ambient temperature range.

Part Context

This part belongs to the TL431 family of programmable zener diodes widely used in switching power supplies. MCC offers various suffixes indicating different tolerance grades or package variations. The TL431V-TP specifically denotes the version available in the SOT-23 surface-mount package, providing a small-footprint solution for modern electronics manufacturing.

Replacement Considerations

Compatible substitutes include generic TL431 variants from other manufacturers offering similar SOT-23 packaging and 36 V maximum ratings. Verify pinout compatibility and ensure equivalent temperature compensation performance. Check for identical electrical parameters regarding minimum operating current and output voltage adjustability.
