Low voltage adjustable precision shunt regulators
Low voltage three-terminal shunt regulator family with an output voltage range between Vref (1.24 V) and 18 V, to be set by two external resistors.
The TLVH431 family consists of 13 versions and provides a choice of three different reference voltage tolerances. The standard operating temperature range is -40 °C to 125 °C. Other options include normal or mirrored pinning in the 3-pin SOT23 SMD plastic package option, and a choice of 0 °C to 70 °C or -40 °C to 85 °C temperature range in standard and A-grade tolerances. Also a 5-pin SOT753 package option is available in each tolerance.
Features and benefits
- Programmable output voltage up to 18 V
- Three different reference voltage tolerances:
- Standard grade: 1.5 %
- A-Grade: 1 %
- D-Grade: 0.75 %
- Typical temperature drift: 4 mV (in a range of -40 °C up to 125 °C)
- Low output noise
- Typical output impedance: 0.1 Ω
- Sink current capability: 0.08 mA to 70 mA
- AEC-Q100 qualified (grade 1)
Applications
- Shunt regulator
- Precision current limiter
- Precision constant current sink
- Isolated feedback loop for Switch Mode Power Supply (SMPS)

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
