Figure 8 and Figure 9 show how the evaluation board is
connected to a voltage source and an ammeter for ground
current measurements. A resistor can be used as the load for the
regulator. Ensure that the resistor has a power rating adequate
to handle the expected power dissipation. Alternatively, an
electronic load can also be used in place of a resistor. Ensure
that the voltage source used can supply enough current for the
expected load levels.
Use the following steps to connect to a voltage source and
ammeter:
1. Connect the positive terminal (+) of the voltage source to
the VIN pad on the evaluation board.
2. Connect the positive terminal (+) of the ammeter to one of
the GND pads of the evaluation board.
3. Connect the negative terminal (−) of the ammeter to the
negative (−) terminal of the voltage source.
4. Connect a load between the negative (−) terminal of the
voltage source and the VOUT pad of the evaluation board.
Then, the voltage source can be turned on. If JP1 is inserted,
connecting EN to VIN for automatic startup, the regulator
powers up.
GROUND CURRENT CONSUMPTION
Ground current measurements 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 (600 mA). Figure 10 shows the
typical ground current consumption vs. load current at an input
voltage of 3.8 V for an output voltage of 3.3 V.
Figure 10. Ground Current vs. Load Current (I

)
When the device is disabled (EN = GND), the ground current
drops to less than 2 μA.
