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.
