Overview
The TLVH431AICT is a low-power adjustable shunt voltage reference manufactured by STMicroelectronics. It provides an output voltage range from 1.24 V to 18 V, set via an external resistor divider. The device features an initial accuracy of ±0.5% and a maximum temperature coefficient of 100 ppm/°C. It operates with a cathode current range of 100 µA to 60 mA and supports a maximum series input voltage of 18 V. The component is housed in a SOT-323-6L surface-mount package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Adjustable output voltage capability spanning 1.24 V to 18 V using external resistors
- Low operating current consumption suitable for power-restricted designs
- Guaranteed temperature stability across the full industrial operating range
- Compact surface-mount packaging designed for space-saving applications
Applications
- Battery chargers
- Switch mode power supplies
- Battery operated equipment
- Data acquisition systems
- Computers
Procurement Notes
Verify the specific suffix 'AICT' corresponds to the required 0.5% tolerance and SOT-323-6L package configuration. Confirm that the 18 V maximum input rating aligns with system requirements, as other variants may support higher voltages. Ensure the selected reel or cut tape quantity matches production needs without exceeding minimum order constraints defined by the distributor.
Selection Notes
Select this component when precise voltage referencing is required in compact, battery-powered devices. The 0.5% accuracy offers a balance between cost and performance compared to tighter tolerances. Consider the 100 µA minimum operating current when designing bias circuits to ensure stable regulation under light load conditions.
Part Context
This part belongs to the TLVH431 family of three-terminal adjustable shunt voltage references. The family includes variants with different accuracies (0.25%, 1%, 1.5%) and packages (SOT-23-3L, SOT-23-5L). The TLVH431AICT specifically denotes the 0.5% precision version in the SOT-323-6L package, distinguishing it from the standard TL431 which typically supports higher voltages.
Replacement Considerations
Publicly confirmed equivalent substitutes include the TLVH431BICT from STMicroelectronics, which shares similar electrical characteristics but may differ in initial accuracy specifications.
