LT3015 系列 - 具精准电流限值的 1.5A、低噪声、负线性稳压器
LT®3015 系列是一款具快速瞬态响应的低噪声、低压差、负线性稳压器。在 310mV 的典型压差电压条件下，该器件能够提供高达 1.5A 的输出电流。LT3015 的工作静态电流通常为 1.1mA，并在停机模式中减小至 <1μA。在压差条件下，静态电流也处于良好受控状态。除了快速瞬态响应之外，LT3015 还可提供非常低的输出噪声，从而使其非常适合那些对噪声敏感的应用。
LT3015 稳压器可在采用一个 10μF (最小值) 输出电容器时实现稳定。另外，该稳压器还可以使用小的陶瓷电容器，而不像其他稳压器常见的那样必需增加 ESR。内部保护电路包括反向输出保护、具折返的精准电流限值以及具迟滞的热限制。
LT3015 稳压器可提供 -2.5V、-3V、-3.3V、-5V、-12V 和 -15V 固定输出电压，以及用作一款具一个 -1.22V 基准电压的可调型器件。该器件提供的封装型式包括 5 引脚 TO-220 和 DD-Pak、耐热性能增强型 12 引脚 MSOP 以及扁平 (高度仅为 0.75mm) 8 引脚 3mm x 3mm DFN 封装。
