Low Voltage Precision

Adjustable Shunt Regulator

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.
