ADP7156CP-3.3EVALZ
ADDITIONAL EQUIPMENT NEEDED
A dc power supply
Multimeters for voltage and current measurements
Electronic or resistive loads
GENERAL DESCRIPTION
The ADP7156CP-3.3EVALZ evaluation board demonstrates the
operation and functionality of the ADP7156 ultralow noise,
1.2 A, fixed output, radio frequency (RF) linear regulator in a
10-lead LFCSP package.
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, and a voltmeter or an
ammeter.

Complete specifications for the ADP7156 ultralow noise, 1.2 A,
linear regulator are available in the ADP7156 data sheet available
from Analog Devices, Inc., and should be consulted in con-
junction with this user guide when using the evaluation board.
