Analog Devices Inc. EVAL-ADP7159 Evaluation Boards include ADP7159CP-04-EVALZ and ADP7159RD-04-EVALZ Evaluation Boards to demonstrate the operation and functionality of the ADP7159 Voltage Regulator. The ADP7159CP-04-EVALZ Evaluation Board includes an ADP7159 regulator in a 10-lead LFCSP package. The ADP7159RD-04-EVALZ Evaluation Board includes an ADP7159 regulator in an 8-lead SOIC package. Device measurements like line and load regulation, dropout voltage, and ground current, can be demonstrated using only a single voltage supply, load resistors, and a voltmeter or an ammeter.
