EVALUATION KIT CONTENTS
ADM7154CP-3.3EVALZ, ADM7154RD-1.8EVALZ, or
ADM7155CP-02-EVALZ evaluation board
ADDITIONAL EQUIPMENT NEEDED
DC power supply
Multimeters for voltage and current measurements
Electronic or resistive loads
GENERAL DESCRIPTION
The ADM7154CP-3.3EVALZ, ADM7154RD-1.8-EVALZ, and
ADM7155CP-02-EVALZ evaluation boards are used to
demonstrate the functionality of the ADM7154 and ADM7155
linear regulators, respectively.
Simple device measurements, such as line and load regulation,
dropout, and ground current, can be demonstrated with just a
single voltage source, a voltmeter, an ammeter, and load resistors.
For more details about the linear regulators, refer to the
ADM7154 and ADM7155 data sheets.

EVALUATION BOARD HARDWARE
EVALUATION BOARD CONFIGURATIONS
The evaluation boards arrive supplied with different
components depending on which version is ordered. Components
common to both versions are C1, C2, C3, C4, C5, J1, and J2.
Resistors R1 and R2 are used for the ADM7155 adjustable
output option. The output voltage (V
OUT
) is set by
V
OUT
= 1.2 V × (1 + R1/R2)
