Product Summary
The TLV431CDBVR is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (1.24 V) and 6 V with two external resistors. The TLV431CDBVR operates from a lower voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.
Parametrics
TLV431CDBVR absolute maximum ratings: (1)Cathode voltage, VKA: 7V; (2)Continuous cathode current range, IK: -20 mA to 20 mA; (3)Reference current range, Iref: -0.05 mA to 3 mA; (4)Package thermal impedance, θJA: D package 97℃/W; (5)DBV package: 206℃/W; (6)DBZ package: 206℃/W; (7)DCK package: 252℃/W; (8)LP package: 140℃/W; (9)PK package:52℃/W; (10)Operating virtual junction temperature: 150℃; (11)Storage temperature range, Tstg: 65℃ to 150℃.
