OUTPUT VOLTAGE MEASUREMENT
Figure 3 shows how the evaluation board can be connected to a
voltage source and a voltmeter for basic output voltage accuracy
measurements. A resistor can be used as the load for the regulator.
voltage source and a voltmeter for basic output voltage accuracy
measurements. A resistor can be used as the load for the regulator.
Ensure that 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. In addition, ensure that the voltage
source can supply enough current for the expected load levels.

can be used as an alternative. In addition, ensure that the voltage
source can supply enough current for the expected load levels.
Follow these steps to connect to a voltage source and voltmeter:
1. Connect the negative terminal (−) of the voltage source to
one of the GND pads on the evaluation board.
2. Connect the positive terminal (+) of the voltage source to
the VIN pad of the evaluation board.
3. Connect a load between the VOUT pad and one of the
GND pads.
4. Connect the negative terminal (−) of the voltmeter to one
of the GND pads.
5. Connect the positive terminal (+) of the voltmeter to the
VOUT pad.
The voltage source can now be turned on. If J1 is inserted
(connecting EN to VIN for automatic startup), the regulator
powers up.

powers up.
If the load current is large, connect the voltmeter as close as
possible to the output capacitor to reduce the effects of IR drops.
