What are its key features?
Adjustable shunt voltage reference with output range from 2.5V to 36V, high accuracy (±0.4%), low temperature drift (~20 ppm/°C), low noise, strong stability with capacitive loads, and wide sink current capability (1mA to 100mA). It also operates over a wide temperature range (-40°C to +125°C) and comes in a compact SOT-23-3 package.
What is it used for?
Commonly used in power supplies, voltage regulation circuits, feedback control loops, battery chargers, and reference voltage generation in analog and mixed-signal systems.
Are there alternative parts?**
Yes, alternatives include TL431 series (from Texas Instruments, onsemi, etc.), LM431, KA431, and other adjustable shunt references with similar voltage range, accuracy, and package options.
