TLVH431LIL3T

Product Overview

The TLVH431LIL3T from STMicroelectronics is an Active shunt voltage reference IC with an adjustable output. The supplied data lists a minimum/fixed output voltage of 1.24 V, a maximum output voltage of 18 V, and an output current of 60 mA. The device has a ±1.5% tolerance, a 100 ppm/°C temperature coefficient, and a 30 mVrms noise value over 10 Hz to 10 kHz. It is supplied in a surface-mount TO-236-3, SC-59, SOT-23-3 package and is rated for an operating temperature range of -40°C to 125°C (TA). The 200 µA cathode current is also included in the supplied data.

Key Features

• Shunt reference architecture with adjustable output and supplied voltage range from 1.24 V to 18 V.
• Output current rating of 60 mA, with a listed cathode current of 200 µA.
• ±1.5% tolerance and 100 ppm/°C temperature coefficient as specified in the supplied data.
• Surface-mount SOT-23-3 package with an operating temperature range of -40°C to 125°C (TA).
• 10 Hz to 10 kHz noise value of 30 mVrms, with Active lifecycle status.

Applications

• Providing a selectable reference level for analog measurement inputs in compact board designs.
• Establishing a known voltage point in power-supply regulation and monitoring networks.
• Setting a reference node in sensor signal-conditioning circuits that require adjustable output voltage.

Design & Procurement Notes

Designers should compare the required output voltage against the supplied 1.24 V to 18 V adjustable range and verify that the 60 mA output current and 200 µA cathode current fit the circuit budget. The ±1.5% tolerance and 100 ppm/°C temperature coefficient should be evaluated against accuracy requirements across the -40°C to 125°C operating temperature range. The 30 mVrms noise value over 10 Hz to 10 kHz should be considered for reference paths where noise affects measurement stability. The SOT-23-3 surface-mount package supports compact layouts, while the Active lifecycle status should be checked for long-term procurement planning.
