概述

The ADM7160 evaluation boards demonstrate the operation and functionality of the ADM7160 ultralow noise, 200 mA, linear regulator.

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

Complete specifications for the ADM7160 ultralow noise, 200 mA, linear regulator are available in the ADM7160 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using the evaluation boards.
