SHUTDOWN CURRENT MEASUREMENT
Figure 13 and Figure 14 show how the evaluation boards can be
connected to a voltage source and an ammeter for shutdown
current measurements. The ammeter can also be connected to
the GND terminal to measure the ground current, which is equal
to the shutdown current when EN is tied to ground. Figure 12
shows the typical shutdown current consumption for various
input voltages.

Follow these steps to connect to a voltage source and ammeter:
1. Connect the positive terminal (+) of the voltage source to
the (+) of the ammeter.
2. Connect the negative (−) terminal of the voltage source to
GND pad and EN pin on the evaluation board.
3. Connect the negative terminal (−) of the ammeter to the
VIN pad on the evaluation board.
The voltage source can now be turned on.
