TL431IPK3

The TL431IPK3 is designed as three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors.

TL431IPK3 has seven features. (1) Its operation temperature range from −40°C to 125°C. (2) Its reference voltage tolerance at 25°C would be 0.5% for B grade and would be 1% for A grade and would be 2% for standard grade. (3) Its typical temperature drift would be 6mV (C temp) and 14mV (I temp, Q temp). (4) It would have low output noise. (5) Its would have 0.2 typical output impedance. (6) Its sink-current capability would be from 1mA to 100mA. (7) Its adjustable output voltage would be from Vref to 36V. That are all the main features.

Some absolute maximum ratings of TL431IPK3 have been concluded into several points as follow. (1) Its cathode voltage, Vka would be 37V. (2) Its continuous cathode current range, Ika would be from -100mA to 150mA. (3) Its reference input current range would be from -50A to 10mA. (4) Its operating virtual junction temperature, Tj would be 150°C. (5) Its storage temperature range, Tstg would be from -65°C to 150°C. It should be noted that stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device.

Also some electrical characteristics about TL431IPK3. (1) Its reference voltage would be min 2440mV and typ 2495mV and max 2550mV. (2) Its deviation of reference voltage over full temperature range would be typ 4mV and max 25mV. (3) Its reference current would be typ 2uA and max 4uA. (4) Its deviation of reference current over full temperature range would be typ 0.4uA and max 1.2uA. (5) Its minimum cathode curent for regulation would be typ 0.4mA and max 1mA. And so on.
