LT1086 - 1.5A、可调及固定 2.85V、3.3V、3.6V、5V、12V 低压差正稳压器
LT®1086 专为提供高达1.5A 的输出电流而设计。所有的内部电路均设计以在低至 1V 的输入至输出压差条件下运作，而且将压差电压作为负载电流的一个函数进行了全面的规格拟订。压差电压在多个工作点 (最高达 1.5V) 和最大输出电流条件下得到保证。当负载电流降低时，压差减小。片内修整可将基准 / 输出电压调节至 1%。另外，还可对电流限值进行调整，从而最大限度地减小过载情况下稳压器和电源电路上承受的应力。
LT1086 与老式三端可调稳压器的引脚兼容。在这些器件上需要使用一个最小 10μF 的输出电容器。
LT1086 拥有卓越的电压和负载调节性能指标以及超过 75dB 的纹波抑制能力，即使在1.5A的最大负载电流条件下也不例外。LT1086 是具有一个复合 NPN 输出级的浮动架构。所有的静态电流和用于输出级的驱动电流均流至负载，从而提升了效率。
LT1086采用 3 引脚 TO-220 封装和节省空间的表面贴装型 3 引脚 DD 封装。
