2.3 TESTING THE MIC38300 EVALUATION BOARD
In order to test the MIC38300 Evaluation Board, follow the next steps:
1. Apply the appropriate input voltage, V
IN
= 3.3V.
2. Use a multimeter to measure the input voltage and the output voltage. V
R
should
be 1.8V.
3. Connect an electronic load between V
OUT
and GND set to maximum load current
of 2.2A for the MIC38300 device. Resistors can also be used between the V
OUT
and GND terminals as a load. Test V
R
(should be 1.8V).
4. Connect Jumper on the EN header. Test VR; it should be 0V.
5. Remove the jumper from the EN header. VR should be 1.8V.
6. By adjusting the input voltage or the load while still maintaining nominal operating
conditions, the LDO will remain in regulation.
