Power Dissipation (continued)

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.

8.5 Noise Performance

Typical 0.1-Hz to 10-Hz voltage noise can be seen in Figure 18 . Device noise increases with output voltage and

operating temperature. Additional filtering can be used to improve output noise levels, although care must be

taken to ensure the output impedance does not degrade ac performance. Peak-to-peak noise measurement

setup is shown in Figure 18.
