GROUND CURRENT CONSUMPTION
Ground current measurement is a way of determining how much
current the internal circuits of the regulator are consuming while
performing the power switch function. To be efficient, the power
switch must consume as little current as possible. Figure 11 shows
the typical ground current consumption for various load levels.
