Description
The TS431 is a low-voltage, three-terminal,
programmable shunt voltage reference.
The output voltage can be set to any value
between V
resistors.
The TS431 is able to operate at a lower voltage
(1.24V) and lower cathode current than the widely
used TL431 and TL1431 shunt voltage reference.
When driving an optocoupler, the TS431 is
particularly useful for regulating 3.3V switching
power supplies.

Low voltage operation: 1.24 to 6V
2%, 1% and 0.5% voltage precision
Wide operating range cathode current: 60µA to
30mA
Low output impedance: 0.2Ω
Typically stable for any capacitive loads
ESD protection:
