... PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. Evaluation Board User Guide GENERAL DESCRIPTION This user guide explains the functionality of the ADP124/ ADP125 linear regulators. Simple device measurements such as line and load regulation, dropout voltage, and ground current can be achieved with only a single voltage supply, a voltage meter, a current meter, and load resistors ...

... J1. Figure 4, Figure 5, and Figure 6 show the schematics of the various ADP124 and ADP125 evaluation board configurations. Table 1 describes the components. The ADP125 is the same as the ADP124 except that the output voltage dividers are internally disconnected and the feedback input of the error amplifiers is brought out for each output. The ...
