DESCRIPTION
Demonstration circuit SCP-ADP7142-EVALZ is a 40V,
200mA low dropout (LDO) regulator designed to allow low
noise operation in noise sensitive circuits. It is easily con-
figured for a wide output range and can provide extremely
quiet operation with its high PSRR.
Like all boards in the Signal Chain Power series, this board
is designed to be easily plugged into other SCP boards to
form a complete signal chain power system, enabling fast
evaluation of low power signal chains. To evaluate this
board, some universal SCP hardware is required, namely:
SCP-INPUT-EVALZ
SCP-OUTPUT-EVALZ
SCP-1X5BKOUT-EVALZ
SCP-THRUBRD-EVALZ

To properly evaluate SCP series demo boards, you will
need the SCP Configurator companion software. SCP
Configurator can help you choose the right board and to-
pology for your design.
Note that this Demo Manual does not cover details im-
portant to the operation and configuration regarding the
ADP7142. Please refer to the
