Figure 9.
Figure 9 shows how the evaluation board can be connected
to a voltage source and a current meter for ground current
measurements. A resistor can be used as the load for the
regulator. Ensure the resistor has a power rating adequate to
handle the power expected to be dissipated across it. An electronic
load can be used as an alternative. Ensure the voltage source
used can supply adequate current for the expected load levels.
Follow these steps to connect to a voltage source and current meter:
largest load level (50 mA). Figure 10 shows the typical ground
current consumption for various load levels.

GROUND CURRENT CONSUMPTION
Ground current measurements are a way of determining how
When the device is disabled (EN = 0 V), ground current is
reduced to less than 1 μA.
Note that larger ground current levels are observed when using
an evaluation board with R1 and R2 present.
much current the regulator’s internal circuits are consuming,
while performing the regulation function. To be efficient, the
regulator must consume as little current as possible. Typically,
the regulator consumes maximum current when supplying its
