    DC995A

    LT3080EDD演示板 | 单电阻可编程线性稳压器，2.3V ≤ VIN ≤ 25V，VOUT = 0.6V/1.0V/1.2V/1.5V/1.8V/2.5V/3.3V/5V(1.1A)

    产品详情

    演示电路995A是一款可调1.1A线性稳压器，内置LT3080。该新型稳压器构建为精密电流源和电压跟随器，可用于许多需要高电流、调整为零输出且无需散热器的应用。配合多个电源使用时，该器件会引出调整管的集电极以实现低压差工作。演示板的输入电源电压范围为2.3V至25V。为便于适当调节，LT3080具有控制引脚；此引脚上的电压必须高于输出电压1.2V至1.35V。输出电压通过跳线可选，可设置为1.8V、0V和5V之间的值（使用微调电位计R2）或用户定义值。


    LT3080的一个重要特性是宽输出电压范围。通过使用流经单电阻的基准电流，输出电压可以编程为0V和36V之间的任何电平。由于输入电容电压额定值，DC995A具有25V的较低输入电压。DC995A可用作高电流线性稳压器、用于开关电源的后置稳压器、可变电压源或低输出电压电源。

    产品详情

    演示电路1294A使用LT3080执行四个并联的可调线性稳压器。并行操作需要小型20 mΩ镇流电阻。较短的PCB走线可以轻松实现此目的。并联器件在3.3V时提供高达4.4A的输出电流。


    LT3080构建作为精密电流源和电压跟随器，可用于许多需要高电流、调整为零输出且无需散热器的应用。配合多个电源使用时，该器件会引出调整管的集电极以实现低压差工作。LT3080的输出电压可以编程为在0V和36V之间的任何电平；不过，由于输入电容电压额定值，演示板具有3.8V至25V的较低输入电压范围。
