EVALUATION KIT CONTENTS
ADP7159CP-04-EVALZ or ADP7159RD-04-EVALZ
evaluation board
ADDITIONAL EQUIPMENT NEEDED
A dc power supply
Multimeters for voltage and current measurements
Electronic or resistive loads
GENERAL DESCRIPTION
The ADP7159CP-04-EVALZ and ADP7159RD-04-EVALZ
evaluation boards demonstrate the operation and functionality
of the ADP7159 ultralow noise, 2 A, adjustable output, radio
frequency (RF) linear regulator.
Simple device measurements such as line and load regulation,
dropout voltage, and ground current, can be demonstrated
using only a single voltage supply, load resistors, anda
voltmeter or an ammeter.
Complete specifications forthe ADP7159 ultralow noise, 2 A,
adjustable output, radio frequency (RF) linear regulatorare
available in the ADP7159 data sheet available from Analog
Devices,Inc., and should be consultedin conjunctionwith this
user guide when using the evaluation boards.
