The STMicroelectronics TL431AIL3T is an adjustable shunt voltage reference in a 3-pin SOT-23 package. It has a 2.495V reference voltage and can be programmed with an external resistor divider up to a 36V output, handling as much as 100mA of output current. The TL431AIL3T is a 1% accuracy grade rated for -40C to 105C operation, is lead-free and RoHS compliant, and ships on tape and reel.
Adjustable shunt references are the standard reference and error-amplifier element in isolated switch-mode power supplies, where they set the secondary-side feedback voltage through an optocoupler. They also serve as programmable zener replacements, undervoltage and overvoltage detectors, precision current limits and battery charger setpoints. The 105C top rating extends the usable ambient beyond a commercial-grade part, which is why power supply, adapter and automotive-adjacent designers reach for this version.
Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
