TL432ATA

The TL432ATA is one member of the TL432 series.The TL432 is three-terminal adjustable shunt regulator, 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 (see Figure 17).

Features of the TL432ATA are:(1)low output noise; (2)0.2- typical output impedance; (3)sink-current capability:1 mA to 100 mA; (4)adjustable output voltage:Vref to 36 V.These devices have a typical output impedance of 0.2. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation,adjustable power supplies, and switching power supplies. The TL432 has exactly the same functionality and electrical specifications as the TL431, but has different pinouts for the DBV, DBZ, and PK packages.

The absolute maximum ratings of the TL432ATA can be summarized as:(1)cathode voltage:37V;(2)storage temperature range:-65 to 150;(3)continuous cathode current range:-100 to 150mA;(4)operating virtual junction temperature range:150;(5)reference input current range :-50 A to 10 mA.Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied.Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.The information provided on this page represents TI's knowledge and belief as of the date that it is provided.
