Description
The TS432 is an adjustable low power shunt voltage reference providing an output voltage from 1.
24 V to 10 V over the industrial temperature range (-40° C to +85° C).
Available in SOT23-3 surface mount package, it can be designed in applications where space saving is critical.
The low operating current is also a key advantage for power restricted designs.
In addition, the TS432 is very stable and can be used in a broad range of application conditions.
