产品详情

演示电路 SCP-LT1962-EVALZ 是 20V、300mA 低压降（LDO）调节器，旨在噪声敏感电路中进行低噪声工作。它易于配置用于较宽的输出范围，并具有高 PSRR，操作极为安静。

像信号链电源系列中的所有电路板一样，该板可轻松插入其他 SCP 板中，以形成完整的信号链电源系统，从而能够快速评估低功耗信号链。要评估该评估板，需要一些通用的 SCP 硬件，即：

SCP-INPUT-EVALZ
SCP-OUTPUT-EVALZ
SCP-1X5BKOUT-EVALZ
SCP-THRUBRD-EVALZ

SCP-FILTER-EVALZ
SCP-1X2BKOUT-EVALZ
SCP-5X1-EVALZ

为了正确评估 SCP 系列演示板，您将需要 SCP Configurator 配套软件。SCP Configurator 可以帮助您为您的设计选择正确的电路板和拓扑。

请注意，演示手册并未涵盖关于 LT1962 的操作和配置的重要细节。有关该套件的完整说明，请参考 LT1962 数据手册。

产品详情

Demonstration circuit DC339-B is a low noise micropower voltage regulator using the 300mA output current LT1962 linear regulator in an 8-lead MSOP package. The demo board has an input voltage range from 2.3V to 20V and a jumper-selectable output votlage that can be set to 1.22V, 2.5V, 3.0V, 3.3V, 5V or a user-defined value. The LT1962's low 20µVRMS (10Hz to 100kHz bandwidth) output noise and low 30µA quiescent current make the device ideal for voltage-controlled oscillators, RF power supplies and local regulators in larger systems.
