Product Details

Demonstration circuit SCP-LT1964-EVALZ is a –20V, 200mA Low Dropout (LDO) regulator designed to allow low noise operation in noise sensitive circuits. It is easily configured 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

SCP-FILTER-EVALZ
SCP-1X2BKOUT-EVALZ
SCP-5X1-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 topology for your design.

Note that the Demo Manual does not cover details important to the operation and configuration regarding the LT1964. Please refer to the LT1964 data sheet for a complete description of the part.

Product Details

Demonstration circuit DC437 is a low noise negative micropower voltage regulator using the LT1964 low dropout linear regulator, which comes in a tiny 5-Pin SOT-23 package. The DC437 has an input voltage range from –2.3V to –20V, and is capable of delivering up to 200mA of output current. There are two circuits on this demo board: one uses the LT1964ES5-BYP which allows the internal reference to be bypassed to reduced output voltage noise, and the other uses the LT1964ES5-SD which has the shutdown feature. The output voltage is jumper-selectable and can be set to -1.22V, -5V or a user-determined value.
