TS2431
Adjustable shunt voltage reference
Datasheet -production data Industrial temperature range: -40 to + 105
°C
Performance compatible with industrystandard TL431 Applications Computers
Instrumentation
Battery chargers
Switch mode power supplies
Battery-operated equipment Description Features Adjustable output voltage: 2.5 to 24 V
Precision selection at 25 °C: ± 2%, ± 1% and
± 0.5%
Sink current capability: 1 to 100 mA The TS2431 is an adjustable shunt voltage
reference with guaranteed temperature stability
over the entire temperature range of operations
from -40 to + 105 °C. The output voltage may be
set to any value between 2.5 and 24 V with an
external resistor bridge. Available in an SOT233L surface mount package, the device can be
implemented for those applications where spacesaving is of the utmost importance. Table 1: Device summary
