Adjustable shunt voltage reference - STMicroelectronics
Description
TS431
Adjustable shunt voltage reference IC (automotive for SOT23-5)
Z TO92 (plastic package)
L SOT23-5 (plastic micropackage)
Datasheet - production data
Description
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.
Features
AEC-Q100 qualified (SOT23-5) Low voltage operation: 1.
24 to 6 V 2%, 1% and 0.
