Rated for 100 mA continuous output current and a minimum cathode current of 700 µA, the part can drive optocoupler LEDs directly or bias a pass transistor without a separate pre-regulator. The SOT-23-3 package keeps the footprint small, making it a common choice for space-constrained designs where a TO-92 or SOIC-8 would be overkill. The surface-mount SOT-23-3 package mates with standard reflow profiles and is compatible with both lead-free and tin-lead solder processes.","metaTitle":"TL431AQDBZT Shunt Regulator, 2.495V ±1%, SOT-23-3, Active","metaDescription":"TL431AQDBZT adjustable shunt regulator, 2.495V reference, ±1% tolerance, 100 mA output, -40°C to 125°C.
