TS431：Low voltage adjustable shunt reference

The TS431 is a low-voltage, three-terminal, programmable shunt voltage reference. The output voltage can be set to any value between V_ref(1.24 V) and 6 V using two external resistors. The TS431 is able to operate at a lower voltage (1.24 V) 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 3.3 V switching power supplies.
