Power Supply Rejection Ratio does not vary with load value
nor supply voltage. For easy comparison, Figures 11 and 12
below are created by combining performance graphs found
in the Typical Performance Characteristics section above.

Although supply current may not be a critical specification for
many applications, there is also no real variation in supply
current with no load or with a 600Ω load. This is a result of the
extremely low offset voltage, typically less than 1mV. Figure
13 shows the supply current under the two conditions with no
real difference discernable.
