TS431BILT

TS431BILT is a low-voltage, adjustable shunt voltage reference. 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 suitable for regulating 3.3V switching power supplies.
