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