TS431
Adjustable shunt voltage reference IC (automotive for SOT23-5)
Datasheet -production data Description
Z
TO92
(plastic package) The TS431 is a low-voltage, three-terminal,
adjustable shunt voltage reference. The output
voltage can be set to any value between Vref
(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 widelyused TL431 and TL1431 shunt voltage reference.
When driving an optocoupler, the TS431 is
particularly suitable for regulating 3.3 V switching
power supplies. L
