TLV431A, TLV431B
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 turnon characteristic with a low dynamic
impedance of 0.20 over an operating current range of 100 A 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 TO923 and micro size TSOP5 and
SOT233 packages.
