TLVH431AIL5T

Overview

The TLVH431AIL5T 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 a typical dynamic impedance of 0.22 Ω and operates with a wide current range from 100 µA to 60 mA. It offers a voltage precision of ±0.5% and a maximum temperature coefficient of 100 ppm/°C over the -40°C to +125°C operating temperature range. 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 resistors
• Low operating current consumption suitable for power-restricted designs
• Guaranteed temperature stability across the full industrial temperature range

Applications

• Battery chargers
• Switch mode power supplies
• Battery operated equipment
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'AIL5T' to confirm the ±0.5% tolerance and SOT-23-5 packaging. Ensure compatibility with the required sink current up to 60 mA and input voltage limits of 18 V. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when space-saving surface mount packages are required alongside low quiescent current operation. The ±0.5% initial accuracy makes it suitable for applications demanding higher precision than standard 1% references. Consider the 100 µA minimum operating current requirement for circuit design stability.

Part Context

This part belongs to the TLVH431 series of three-terminal adjustable shunt voltage references. The series includes variants with different accuracies (0.25%, 0.5%, 1%, 1.5%) and packages (SOT23-3L, SOT23-5L, SOT323-6L). The TLVH431AIL5T specifically denotes the 0.5% accuracy grade in the SOT-23-5 package.
