8.6 Power Dissipation

The REF35 voltage references are capable of source up to 10 mA and sink up to 5 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 3:

(3)

where

• PD is the device power dissipation

• TJ is the device junction temperature

• TA is the ambient temperature

• RθJA is the package (junction-to-air) thermal resistance

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 device be operated outside of its

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