TS431 LOW VOLTAGE ADJUSTABLE SHUNT REFERENCE s LOW VOLTAGE OPERATION : 1.24 TO 6V s 2%, 1% AND 0.5% VOLTAGE PRECISION s WIDE OPERATING RANGE CATHODE CURRENT : 60A TO 30mA s LOW OUTPUT IMPEDANCE : 0.2 s TYPICALLY STABLE FOR ANY CAPACITIVE LOADS s ESD PROTECTION : 2kV (Human Body Model) 200V (Machine Model) s 100ppm/°C TEMPERATURE COEFFICIENT DESCRIPTION The TS431 is a low voltage three terminals programmable shunt Voltage Reference. The output voltage can be set to any value between Vref (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 widespread TL431 and TL1431 shunt voltage reference. When driving an optocoupler, the TS431 is particularly interesting to regulate 3.3V switching power supplies.
