Manufacturer

Description

Three-terminal shunt regulator family with an output voltage range between Vref and 36 V, to be set by two external resistors.• The TL431xDBZR types feature an enhanced stability area with a very low load capacity requirement.• The TL431xFDT types offer an enhanced stability area and a higher ElectroMagnetic Interference (EMI) ruggedness, for example,for Switch Mode Power Supply (SMPS) applications.• The TL431xSDT types are designed for standard requirements and linear applications. TL431A Features • Programmable output voltage up to 36 V• Three different reference voltage tolerances: —Standard grade: 2 % —A-Grade: 1 % —B-Grade: 0.5 %• Typical temperature drift: 6 mV (in a range of 0 ℃ up to 70 ℃)• Low output noise• Typical output impedance: 0.2 Ω• Sink current capability: 1 mA to 100 mA• AEC-Q100 qualified (grade 1) TL431A Applications • Shunt regulator• Precision current limiter• Precision constant current sink• Isolated feedback loop for Switch Mode Power Supply (SMPS)
