Product Details

The ADP1764-1.0-EVALZ and ADP1765-1.0-EVALZ fixed evaluation boards and the ADP1764-ADJ-EVALZ and ADP1765- ADJ-EVALZ adjustable evaluation boards demonstrate the functionality of the ADP1764 and the ADP1765 series of linear regulators.

Simple device measurements, such as line and load regulation, dropout voltage, and ground current, are demonstrated with only a single voltage supply, a voltmeter, an ammeter, and load resistors.

The ADP1764 fixed and adjustable evaluation boards are identical to the ADP1765.

For full details on the ADP1764 and the ADP1765 linear regulators, see the ADP1764 and the ADP1765 data sheets, which should be consulted in conjunction with this user guide when using these evaluation boards.
