30mA
■ Low output impedance: 0.2Ω
■ Typically stable for any capacitive loads

Description
The TS431 is a low-voltage, three-terminal,
programmable shunt voltage reference.
The output voltage can be set to any value
between V_ref (1.24V) and 6V with two external
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.
