GENERAL DESCRIPTION
The ADP170/ADP171 evaluation board is used to demonstrate
the functionality of the ADP170/ADP171 linear regulators.
Simple device measurements such as line and load regulation,
dropout, and ground current can be demonstrated with just a
single voltage supply, a voltmeter, a current meter, and load
resistors.

EVALUATION BOARD HARDWARE AND SCHEMATICS
EVALUATION BOARD CONFIGURATIONS
The ADP170/ADP171 evaluation boards come supplied with
different components, depending on which version is ordered.
Components common to all versions are C1 through C6 and J1.
The J2, R1, and R2 components are populated on the adjustable
ADP171 version only; these components are not populated on
the ADP170. C1, C3, and C4 are input capacitors, and C2, C5,
and C6 are output capacitors. These capacitors have different
size footprints to facilitate evaluating the regulator using a
wide variety of components. Figure 2 shows the schematic of
ADP170 evaluation board configuration. Figure 3 shows the
schematic of ADP171 evaluation board configuration.
