DESCRIPTION
The TS824 is a low power shunt voltage reference
featuring a very low temperature coefficient of
50ppm/°C as a maximum value. Providing 1.225V
output voltage, the TS824 operates over the
industrial temperature range (-40 to +85°C). Ideal
for battery-powered equipments where power
conservation is critical, the TS824 is housed in a
tiny SOT23-3 package allowing space saving.
The TS824 is typically stable with a ny capacitive
loads within the entire temperature range. The
product is thus easy to use and t he des ign simplified.
