TLV431A, TLV431B
Low Voltage Precision
Adjustable Shunt Regulator
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
e c o n o m i c a l T O −9 2 −3 a n d m i c r o s i z e T S O P −5 a n d
SOT−23−3 packages.
