Product Details

The ADP172 evaluation board is used to demonstrate the functionality of the ADP172 series of linear regulators. Simple device measurements such as line and load regulation, dropout voltage, and ground current can be demonstrated with only a single voltage supply, a voltmeter, a current meter, and load resistors.

For more information about the ADP172 linear regulator, see the ADP172 data sheet.
