TLVH431LIL3T

Overview

The TLVH431LIL3T is an adjustable shunt voltage reference manufactured by STMicroelectronics. It operates within a wide current range from 100 μA to 60 mA, featuring a typical dynamic impedance of 0.22 Ω. The output voltage is programmable between 1.24 V and 18 V using external resistors. This component offers high temperature stability with a maximum temperature coefficient of 100 ppm/°C across the -40°C to +125°C operating range. It is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Adjustable output voltage set via external resistor divider
• Low power consumption suitable for restricted designs
• High temperature stability over extended industrial ranges

Applications

• Battery-powered portable electronics
• Space-constrained circuit boards
• Precision voltage regulation systems

Procurement Notes

Verify the specific accuracy grade suffix (e.g., L for ±1%) against official datasheets before procurement. Confirm that the SOT-23-3 package dimensions match your PCB footprint requirements. Ensure the selected variant meets the required thermal performance specifications for your intended operating environment.

Selection Notes

Select this component when low quiescent current and small form factor are critical design constraints. The device is appropriate for applications requiring stable reference voltages under varying thermal conditions. Consider the available accuracy grades to balance cost against precision requirements.

Part Context

This part belongs to the TLVH431 series, designed as a low-power alternative to standard shunt references. It addresses modern demands for miniaturization and energy efficiency in consumer and industrial electronics while maintaining reliable voltage regulation capabilities.

Replacement Considerations

Check for pin-compatible alternatives such as the TLVH431BIL3T if higher initial accuracy is required. Verify that any substitute maintains the same SOT-23-3 package and electrical characteristics.
