Overview
The TS431ACX RFG is a low-voltage, three-terminal adjustable shunt voltage reference manufactured by Taiwan Semiconductor. It operates within an output voltage range of 2.495 V to 36 V and features an initial accuracy of 1%. The device has a maximum series reference input voltage of 2.52 V and supports a maximum shunt current of 100 mA with a minimum operating current of 1 mA. It utilizes an SOT-23-3 surface-mount package and is qualified under AEC-Q101 standards for automotive applications. The component functions within a temperature range of 0°C to +70°C.
Feature Summary
- Adjustable shunt regulation capability with precise voltage referencing
- Automotive-grade qualification ensuring reliability in harsh environments
- Compact SMD/SMT packaging for efficient board space utilization
Applications
- Precision voltage regulation in switching power supplies
- Reference voltage sources for analog-to-digital converters
- Optocoupler driving circuits in isolated power systems
Procurement Notes
Verify the specific suffix RFG against the manufacturer's official datasheet to confirm reel specifications and tape-and-reel dimensions. Ensure the AEC-Q101 qualification status aligns with your project's automotive requirements. Cross-reference the SOT-23-3 package outline with your PCB footprint library to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a 1% accuracy shunt reference is required for automotive or industrial applications. Consider the 100 mA cathode current limit for load handling capabilities. Verify that the 0°C to +70°C operating temperature range meets the environmental constraints of the target system design.
Part Context
This part belongs to the TS431xx series of programmable shunt regulators. It serves as a direct replacement for industry-standard TL431 devices but offers specific automotive qualification through AEC-Q101. The series provides a cost-effective solution for voltage monitoring and regulation tasks requiring high precision and stability.
Replacement Considerations
Direct pin-compatible substitutes include the TL431AIDBZR and LM431CIM3/NOPB. Verify that alternative parts meet the same AEC-Q101 automotive qualification if required by the application.
