Overview
The TL431AIL5T is an adjustable shunt voltage reference manufactured by STMicroelectronics, housed in a SOT-23-5 surface-mount package. It provides an output voltage range from 2.495 V to 36 V with a tolerance of ±1%. The device supports a cathode current range of 700 µA to 100 mA and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Adjustable output voltage set between 2.495 V and 36 V using external resistors
- High precision with ±1% initial accuracy tolerance
- Wide operating temperature range suitable for industrial applications
Applications
- Precision voltage references in power supply circuits
- Voltage regulation in switching mode power supplies
- Temperature compensation circuits requiring stable reference voltages
Procurement Notes
Verify the specific suffix 'L5' corresponds to the SOT-23-5 package and tape-and-reel configuration required for your assembly process. Confirm that the ±1% tolerance meets your circuit design specifications. Ensure compatibility with the -40°C to +105°C operating temperature range for your intended environment. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a compact SOT-23-5 footprint is required for adjustable voltage referencing. It is suitable for designs needing ±1% accuracy over a wide industrial temperature range. Consider the 100 mA sink current capability for load requirements. Compare against other TL431 variants if different tolerances or packages are needed.
Part Context
This part belongs to the TL431 family of adjustable shunt regulators, widely used as precision voltage references. It serves as a drop-in replacement for similar devices from other manufacturers, offering comparable performance in terms of voltage range and stability. The STMicroelectronics version ensures automotive-grade reliability features where applicable.
Replacement Considerations
Direct substitutes include the TL431ACDBVTG4 from Texas Instruments and the TL431AW5-7 from Diodes Incorporated. These alternatives share similar electrical characteristics and pinouts but may differ in packaging or specific tolerance grades.
