Stability
The IRU1160 requires the use of an output capacitor as
part of the frequency compensation in order to make the
regulator stable. Typical designs for the microproces-
sor applications use standard electrolytic capacitors with
typical ESR in the range of 50 to 100m V and an output
capacitance of 500 to 1000 m F. Fortunately as the ca-
pacitance increases, the ESR decreases resulting in a
fixed RC time constant. The IRU1160 takes advantage
of this phenomena in making the overall regulator loop
stable.
Assuming, the following conditions:
V OUT = 2.8V
V IN = 3.3V
V CTRL = 5V
I OUT = 3A (DC Avg)
Calculate the maximum power dissipation using the fol-
lowing equation:

P D = I OUT 3 (V IN - V OUT )+ CTRL OUT
