Low Voltage Precision  
Adjustable Shunt Regulator  
The TLV431A and B series are precision low voltage shunt  
regulators that are programmable over a wide voltage range of 1.24 V  
to 16 V. The TLV431A series features a guaranteed reference accuracy  
of 1.0% at 25°C and 2.0% over the entire industrial temperature  
range of −40°C to 85°C. For TLV431B series, the accuracy is even  
higher, it’s 0.5% and 1.0% respectively. These devices exhibit a  
sharp low current turn−on characteristic with a low dynamic  
impedance of 0.20 W over an operating current range of 100 mA to  
20 mA. This combination of features makes this series an excellent  
replacement for zener diodes in numerous applications circuits that  
require a precise reference voltage. When combined with an  
optocoupler, the TLV431A/B can be used as an error amplifier for  
controlling the feedback loop in isolated low output voltage (3.0 V to  
3.3 V) switching power supplies. These devices are available in  
economical TO−92−3 and micro size TSOP−5 and  
SOT−23−3 packages.
