TS824-2.5 HIGH THERMAL STABILITY MICROPOWER SHUNT VOLTAGE REFERENCE LOW Tc: 50 ppm/C MAXIMUM 2.5V OUTPUT VOLTAGE LOW OPERATING CURRENT: 60A max 25C HIGH PRECISION AT 25C: 0.5% AND 1% STABLE WHEN USED WITH CAPACITIVE LOADS INDUSTRIAL TEMPERATURE RANGE: -40 to +85C L DESCRIPTION SOT23-3L The TS824-2.5 is a low power shunt voltage (Plastic Micropackage) 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 +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. THJA Note 2: The Human Body Model (HBM) is defined as a 100pF capacitor discharge through a 1.5k resistor into each pin. The Machine Mode (MM) is defined as a 200pF capacitor discharge directly into each pins.
