Description

The TL431ACLP belongs TL431 family. The TL431is three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The TL431ACLP output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors (see Figure 17). These devices TL431ACLP have a typical output impedance of 0.2 Ω. 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 and DBZ packages. Both the TL431 and TL432 devices are offered in three grades, with initial tolerances (at 25°C) of 0.5%, 1%, and 2%, for the B, A, and standard grade, respectively. In addition, low output drift vs temperature ensures good stability over the entire temperature range. The TL43xxC devices are characterized for operation from 0°C to 70°C, the TL43xxI devices are characterized for operation from −40°C to 85°C, and the TL43xxQ devices are characterized for operation from −40°C to 125°C.

The features of TL431ACLP can be summarized as (1)operation from -40°C to 125°C: 0.5% . . . B grade; 1% . . . A grade; 2% . . . standard grade; (2)typical temperature drift (TL431B): 6 mV (C temp); 14 mV (I Temp, Q temp); (3)low output noise; (4)0.2- typical output impedance; (5)sink-current capability . . . 1 mA to 100 mA; (6)adjustable output voltage . . . vref to 36 V.

The absolute maximum ratings of TL431ACLP are (1)cathode voltage, VKA (see Note 1: Voltage values are with respect to the ANODE terminal, unless otherwise noted.): 37 V; (2)continuous cathode current range, IKA : -100 mA to 150 mA; (3)reference input current range: -50 A to 10 mA; (4)operating virtual junction temperature, TJ: 150°C; (5)storage temperature range, Tstg: -65°C to 150°C( 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.)
