TS824-1.2 HIGH THERMAL STABILITY MICROPOWER SHUNT VOLTAGE REFERENCE LOW Tc: 50 ppm/C MAXIMUM 1.225V OUTPUT VOLTAGE LOW OPERATING CURRENT: 45A max 25C HIGH PRECISION AT 25C: 1% STABLE WHEN USED WITH CAPACITIVE LOADS INDUSTRIAL TEMPERATURE RANGE: -40 to +85C L DESCRIPTION SOT23-3L (Plastic Micropackage) 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 +85C). 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 any capacitive PIN CONNECTIONS (top view) loads within the entire temperature range. The product is thus easy to use and the design simpli- fied.

It can be calculated using T (maximum junction tem- JMAX perature), R (Thermal resistance junction to ambient) and T (Ambient temperature). The maximum power dissipation formula at any THJA A temperature is P = (T - T ) / R R is 340C/W for the SOT23-3 package. DMAX JMAX A THJA.
