immunity to changes in load, input voltage, power
dissipation, and temperature. Line and load regulation are
tested with a pulse of short duration (< 100 s) and are
strictly a function of electrical gain. However, pulse widths
of longer duration (> 1.0 ms) are sufficient to affect
temperature gradients across the die. These temperature
gradients can cause a change in the output voltage, in
addition to changes caused by line and load regulation.
Longer pulse widths and thermal gradients make it
desirable to specify thermal regulation.

specified time, and is expressed as a percentage output
voltage change per watt. The change in dissipated power

can be caused by a change in either the input voltage or the
load current. Thermal regulation is a function of IC layout
and die attach techniques, and usually occurs within 10 ms
of a change in power dissipation. After 10 ms, additional
changes in the output voltage are due to the temperature
