Overview
The TS431BIYLT is an adjustable shunt voltage reference IC from STMicroelectronics, designed for automotive applications in a SOT-23-5 package. It offers an initial accuracy of 0.5% and operates within a cathode current range of 60 µA to 30 mA. The output voltage is adjustable between 1.24 V and 6 V, with a maximum input voltage of 10 V. It features a temperature coefficient of 100 ppm/°C and functions across a temperature range of -40°C to +125°C. The device is AEC-Q100 qualified.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- High precision with 0.5% initial accuracy
- Low output impedance typically stable for any capacitive loads
- Integrated ESD protection meeting Human Body Model (2kV) and Machine Model (200V) requirements
Applications
- Regulating 3.3 V switching power supplies when driving optocouplers
- Replacing TL431 and TL1431 references in low-voltage designs
- Precision voltage referencing in automotive electronic systems
Procurement Notes
Verify the specific suffix 'BIYLT' against official STMicroelectronics documentation to confirm the exact accuracy grade and packaging configuration. Ensure the component meets AEC-Q100 requirements for your target automotive application. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement specifications.
Selection Notes
Select this component when a low-voltage adjustable reference with high precision is required for automotive environments. It serves as a direct alternative to TL431 devices, offering operation at lower voltages and currents. The SOT-23-5 package facilitates compact surface-mount designs where space is constrained.
Part Context
The TS431 series represents a family of low-voltage, three-terminal programmable shunt voltage references. The TS431BIYLT variant specifically denotes the 0.5% accuracy grade housed in a SOT-23-5 plastic micropackage. This series enables designers to set output voltages between 1.24 V and 6 V using external resistors, providing flexibility for various power management topologies.
Replacement Considerations
TS431AIYLT (1% accuracy), TS431ILT (2% accuracy). These variants share identical pinouts and electrical characteristics except for initial accuracy tolerance.
