Overview
The TLVH431LICT is a low-power adjustable shunt voltage reference manufactured by STMicroelectronics. It provides an output voltage range from 1.24 V to 18 V with an initial accuracy of ±1.5%. The device features a temperature coefficient of 100 PPM/°C and supports a maximum shunt current of 60 mA. It is housed in a compact SOT-323-6 package, designed for applications requiring stable voltage references across the entire operating temperature range.
Feature Summary
- Low power consumption design suitable for battery-operated systems
- Guaranteed temperature stability over the full operating range
- Adjustable output voltage via external resistor divider
Applications
- Battery-powered equipment
- Portable instruments
- Voltage regulation circuits
Procurement Notes
Verify the specific suffix 'LI' against the official STMicroelectronics datasheet to confirm package type and tape/reel specifications. Ensure the component status is listed as Active. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the SOT-323-6L package matches the board layout requirements.
Selection Notes
Select this component when a low-cost, adjustable shunt reference is required with moderate precision. The 1.24 V minimum output allows flexibility in setting reference levels. Consider the 60 mA current limit for load driving capabilities. The SOT-323-6 package is ideal for space-constrained designs compared to larger through-hole alternatives.
Part Context
The TLVH431 series belongs to STMicroelectronics' portfolio of precision voltage references. These devices are widely used in industrial and consumer electronics where stable reference voltages are critical. The TLVH431LICT specifically denotes the SOT-323-6 surface-mount variant, offering a balance between performance and footprint size for modern PCB designs.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family or from other manufacturers such as Texas Instruments. Verify that replacement parts meet the 1.24 V to 18 V output range and 100 PPM/°C temperature coefficient requirements. Ensure the alternative device supports the 60 mA shunt current specification.
