TLV431, NCV431, SCV431

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

±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

over an operating current range of 100

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.
