TL431CPWR

Overview

The TL431CPWR is a three-terminal adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of approximately 2.5 V to 36 V, set via two external resistors. The device features a typical dynamic output impedance of 0.2 Ω and supports sink currents from 1 mA to 100 mA. It is housed in an 8-pin TSSOP package with a tape-and-reel configuration. The component is rated for commercial temperature operation between 0°C and 70°C.

Feature Summary

Provides programmable output voltage capability across a wide range using external resistors
Delivers low dynamic output impedance for stable regulation performance
Supports high current sinking capacity suitable for diverse power management applications

Applications

Board-level voltage regulation circuits
Adjustable linear and switching power supplies
General-purpose voltage reference sources

Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-8 surface-mount package and tape-and-reel packaging format. Confirm the 'C' grade designation aligns with the required commercial temperature range of 0°C to 70°C. Ensure compatibility with standard SMD assembly processes for the specified footprint.

Selection Notes

Select this variant when a surface-mount solution is required for space-constrained designs. The TSSOP-8 package offers a compact form factor compared to through-hole alternatives. Verify that the commercial temperature rating meets the environmental requirements of the target application.

Part Context

This component belongs to the widely adopted TL431 family of programmable shunt regulators. It serves as a direct replacement for Zener diodes in many circuit topologies. The device integrates a bandgap reference and error amplifier to achieve precise voltage control.
