Overview
The TL431BIDCKTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a cathode voltage range of 2.5V to 36V and provides a typical initial accuracy of ±0.5%. The device supports a maximum cathode current of 100mA and features a low dynamic output impedance. It is housed in a compact SC-70 (SOT-363) surface-mount package with six pins. The component is designed for automotive applications, ensuring reliability under varying thermal conditions.
Feature Summary
- Provides precise voltage regulation through an adjustable reference mechanism
- Ensures high stability with low dynamic output impedance characteristics
- Supports automotive-grade operational requirements for durability
Applications
- Automotive power supply regulation circuits
- Precision voltage reference sources
- Linear regulator feedback loops
Procurement Notes
Verify the specific suffix 'TG4' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and automotive qualification status. Ensure compatibility with standard SC-70 footprint designs during procurement planning.
Selection Notes
Select this component when a compact surface-mount solution is required for automotive voltage regulation. The ±0.5% accuracy suits applications demanding tighter tolerance than standard industrial variants. Verify that the SC-70 package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the TL431 family of programmable shunt regulators. It serves as a direct replacement for legacy TO-92 versions in modern surface-mount designs. The device integrates a temperature-compensated Zener diode structure to maintain stable performance across the specified operating temperature range.
Replacement Considerations
Direct substitutes include other automotive-grade TL431 variants in SC-70 packages from Texas Instruments. Cross-manufacturer equivalents require verification of pinout compatibility and thermal specifications.
