GENERAL DESCRIPTION
The ADP1712/ADP1713/ADP1714 evaluation boards are used
to demonstrate the functionality of the ADP1712, ADP1713,
and ADP1714 series of linear regulators. Depending on what
component combinations are used, the evaluation board can
be used for ADP1712 fixed output voltage devices with soft
start, ADP1712 adjustable output voltage devices, ADP1713
fixed output voltage devices with a bypass capacitor, and ADP1714
fixed output voltage devices with tracking.
Simple device measurements such as line and load regulation,
dropout, and ground current can be demonstrated with just a
single voltage supply, a voltage meter, a current meter, and load
resistors.
