Detailed Description for TL431AIL3T
Product Overview
TL431AIL3T is an STMicroelectronics shunt voltage reference IC with an adjustable output. The device is specified for output voltages from 2.495 V to 36 V, with a ±1% tolerance and a 100 mA output current. It is supplied in a surface-mount TO-236-3, SC-59, SOT-23-3 package and is used for voltage-reference functions in power-management and analog circuits. The specified cathode current is 700 µA, and the operating temperature range is -40°C to 105°C (TA). This part can be used where a shunt reference is required to establish a known voltage level within its electrical and thermal limits.
Key Features
- Shunt reference topology with adjustable output voltage.
- Output voltage range specified from 2.495 V to 36 V.
- Reference tolerance of ±1%.
- Specified output current of 100 mA.
- Cathode current specified at 700 µA.
- Operating temperature range of -40°C to 105°C (TA).
- Surface-mount package: TO-236-3, SC-59, SOT-23-3.
Applications
- Feedback reference in adjustable power-supply regulation loops.
- Voltage threshold setting in analog monitoring circuits.
- Reference input for sensor signal conditioning and measurement front ends.
- Bias reference for DC/DC converter and power-management designs.
Design & Procurement Notes
Design and procurement decisions should focus on matching the circuit’s required reference voltage, current, tolerance, package, and ambient temperature limits to the device specifications. The adjustable output should be evaluated within the 2.495 V to 36 V range, while the 100 mA output current and 700 µA cathode current should be checked against the external circuit conditions. The ±1% tolerance is relevant when setting reference levels or comparison thresholds. For board layout, confirm that the surface-mount TO-236-3, SC-59, SOT-23-3 footprint is acceptable and that the -40°C to 105°C (TA) operating range covers the expected ambient conditions.
