Description

The TS431ILT is a low-voltage, three-terminal, programmable shunt voltage reference. The output voltage can be set to any value between Vref (1.24V) and 6V with two external resistors.

The TS431ILT 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.
