DESCRIPTION
SOT23-3L
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 voltage, the TS824-2.5
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.
(Plastic Micropackage)
The TS824 is typically stable with any capacitive
loads within the entire temperature range. The
product is thus easy to use and the design simpli-
fied.

Note 1: The maximum power dissipation must be derated at high temperature. It can be calculated using T
(maximum junction tem-

Note 3: Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation and by design.
Note 4: The total tolerance within the industrial range, where the maximum ∆T versus 25°C is 65°C, is explained hereafter:
± 1 % + (± 50 ppm/°C x 65°C) = ± 1.325 %
