DESCRIPTION

Demonstration  circuit  SCP-LT3094-EVALZ features  the 
LT3094,  an  ultralow  noise,  ultrahigh  power  supply 
rejection  ratio  (PSRR)  negative  low  dropout  (LDO) 
regulator. The board operates over an input range of –3.8V 
to –20V, and can deliver up to 500mA output current. 

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-FILTER-EVALZ 

SCP-OUTPUT-EVALZ 

SCP-1X2BKOUT-EVALZ 

SCP-1X5BKOUT-EVALZ 

SCP-5X1-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 

LT3094

Please refer to the 

LT3094 datasheet

 for a com-

plete description of the part. 

Design files for this circuit board are available.
