... V. Insert Jumper J1, and check to see if the output voltage rises to the regulated output voltage (1.8 V for the ADP2107-1.8-EVAL and 2.5 V for the ADP2107-EVAL). If the load is not already enabled, enable the load, and check that it is drawing the proper current and that the output voltage maintains voltage regulation ...

... The ADP2107 evaluation board is supplied fully assembled and tested for proper operation. It comes in two versions: the ADP2107-1.8-EVAL with fixed output voltage of 1.8 V and the ADP2107-EVAL with adjustable output voltage initially set to 2.5 V. The two most common modifications that can be done to the evaluation boards are changing the output voltage and changing the load transient response ...
