GROUND CURRENT CONSUMPTION
Ground current measurements can determine how much
current the internal circuits of the regulator are consuming
while the circuits perform the regulation function. To be
efficient, the regulator needs to consume as little current as
possible. Typically, the regulator uses the maximum current
when supplying its largest load level (300 mA). Figure 9 shows
the typical ground current consumption for various load levels
at an input voltage of 2.3 V. When the device is disabled (EN =
GND), the ground current drops to less than 1 μA.
