DESCRIPTION
The TS824-2.5 is a low power shunt voltage
reference featuring a very low temperature
coefficient of 50ppm/°C as a maximum value.
Providing a 2.5V output vo lta ge, the TS824-2.5
operates over the industrial temperature range
(-40 to +85°C). Ideal for battery-powered
equipments whe re power conservation is critical,
the TS824 is hous ed in a tiny SOT23-3 packa ge
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.
