TLVH431AIL5T

Product Overview

The TLVH431AIL5T from STMicroelectronics is a shunt voltage reference for adjustable reference generation. The output voltage range is 1.24 V to 18 V, with a 60 mA output current and a 200 µA cathode current. It uses a surface-mount SOT-23-5 package and is intended for power management and analog circuit contexts where an adjustable reference point is required.

Key Features

• Shunt voltage reference architecture with an adjustable output
• Output voltage range from 1.24 V to 18 V
• Tolerance of ±0.5%
• Temperature coefficient of 100 ppm/°C
• Output current rating of 60 mA
• Cathode current of 200 µA
• Noise value of 30 mVrms over 10 Hz to 10 kHz
• Operating temperature range of -40°C to 125°C
• Surface-mount SOT-23-5 package
• SC-74A, SOT-753 package case

Applications

• Adjustable reference generation in power management circuits
• Shunt reference bias points in analog signal conditioning designs
• Voltage reference points in board-level measurement and control circuits

Design & Procurement Notes

Designers should consider the 1.24 V to 18 V adjustable range, the 60 mA output current, and the 200 µA cathode current when defining the reference circuit's operating point and load conditions. The ±0.5% tolerance, 100 ppm/°C temperature coefficient, and 30 mVrms noise over 10 Hz to 10 kHz affect accuracy and stability across the -40°C to 125°C operating range. The SOT-23-5 surface-mount package should be accounted for in PCB layout and assembly planning. Designers should also verify that the selected output voltage, load current, and ambient temperature remain within the device operating limits.
