Low Voltage Precision
Adjustable Shunt Regulator
TLV431, NCV431, SCV431
The TLV431A, B and C 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. The TLV431B series features higher reference accuracy
of ±0.5% and ±1.0% respectively. For the TLV431C series, the accuracy
is even higher. It is ±0.2% 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/C 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. www.onsemi.com 12 TO−92
