TL431ACDBZR
Texas InstrumentsTL431ACDBZR is a Texas Instruments adjustable precision shunt regulator in a SOT-23-3 package — the programmable-Zener reference at the heart of isolated power-supply feedback loops. The A grade holds the 2.495 V reference to ±1% (2.470 V to 2.520 V), the output adjusts from Vref to 36 V with two external resistors, cathode current runs 1 mA to 100 mA, reference deviation over the temperature range is 6 mV typical / 16 mV maximum, and minimum cathode current is 0.4 mA typical / 0.6 mA maximum. Selection advice: the code decodes as A grade (1%), C temperature range (0 to +70 °C), DBZ SOT-23 on reel — for a wider temperature range or 0.5% tolerance the grade and temperature letters in the middle of the code change, and same-footprint offers of the looser standard grade are not equivalents. TI lists this code as Active (Production). Parameters verified against Texas Instruments documentation.
