Overview
The TLVH431LIL5T is a low-power adjustable shunt voltage reference manufactured by STMicroelectronics. It operates within an output voltage range of 1.24 V to 18 V, set via external resistors. The device guarantees a voltage precision of 1.5% and maintains a maximum temperature coefficient of 100 ppm/°C across the -40°C to +125°C operating temperature range. It supports a cathode current range from 100 µA to 60 mA with a typical dynamic impedance of 0.22 Ω. The component is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Adjustable output voltage capability ranging from 1.24 V to 18 V using external resistor dividers
- Low operating current consumption of 100 µA at 25 °C for power-restricted designs
- High sink current capability up to 60 mA with guaranteed stability over the full industrial temperature range
Applications
- Battery chargers
- Switch mode power supplies
- Battery operated equipment
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'LIL5T' against official STMicroelectronics documentation to confirm the 1.5% initial accuracy grade and SOT-23-5 packaging. Ensure compatibility with design requirements for the specified 100 ppm/°C temperature coefficient and 18 V maximum input voltage limits before finalizing procurement.
Selection Notes
Select this component when space-saving surface mount packages are required alongside low power consumption. It is suitable for applications needing adjustable reference voltages between 1.24 V and 18 V with moderate precision (1.5%). Consider the 100 µA minimum operating current constraint for circuit design.
Part Context
This part belongs to the TLVH431 series of three-terminal adjustable shunt voltage references. The series offers various accuracy grades and package options, including SOT-23-3L, SOT-23-5L, and SOT323-6L. The TLVH431LIL5T specifically utilizes the SOT-23-5L package variant.
Replacement Considerations
Cross-reference with other manufacturers offering similar shunt references such as the TLV431 family or generic adjustable bandgap references. Verify pinout compatibility and electrical parameter equivalence, particularly regarding the 1.24 V internal reference voltage and sink current capabilities.
