Analog Devices Inc. EVAL-ADP7157 Eval for ADP7147 LDOVoltage Regulator
Analog Devices Inc. EVAL-ADP7157 Evaluation Board demonstrates the operation and functionality of the ADP7157 regulators in a 10-lead LFCSP package. Simple device measurements like line and load regulation, dropout voltage, and ground current can be demonstrated. The board uses only a single voltage supply, load resistors, and a voltmeter or an ammeter.
