TLV431A
Low Voltage Precision
Adjustable Shunt Regulator
The TLV431A series are precision low voltage shunt regulators that
are programmable over a wide voltage range of 1.24 V to 16 V. These
series feature 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.
These devices exhibit a sharp low current turn–on characteristic with a
low dynamic impedance of 0.20
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 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 TSOP–5 and TO–92 packages.
