Thermal Hysteresis (continued)

7.4 Power Dissipation

The REF2125 voltage reference is capable of source and sink up to 10 mA of load current across the rated input

voltage range. However, when used in applications subject to high ambient temperatures, the input voltage and

load current must be carefully monitored to ensure that the device does not exceeded its maximum power

dissipation rating. The maximum power dissipation of the device can be calculated with Equation 2:

where

•

•

•

(2)

Because of this relationship, acceptable load current in high temperature conditions may be less than the

maximum current-sourcing capability of the device. In no case should the part be operated outside of its

maximum power rating because doing so can result in premature failure or permanent damage to the device.
