LT1965的产品详情:

LT1965 是一款低噪声、低压差线性稳压器。该器件可提供 1.1A 的输出电流和一个 310mV 的典型压差。工作静态电流为 500μA (可调版本),并在停机模式中降至 1μA 以下。静态电流处于良好受控状态;与采用其他许多稳压器时不同,它在压降条件下并不上升。LT1965 稳压器具有非常低的输出噪声,因而非常适合于敏感的 RF 和 DSP 电源应用。

输出电压变化范围为 1.20V 至 19.5V。LT1965 稳压器可在采用低至 10μF 的输出电容器时实现稳定。内部保护电路包括反向电池保护、具折返保护功能的电流限制、热限制和反向电流保护。LT1965 系列可提供 1.5V、1.8V、2.5V 和 3.3V 的固定输出电,以及与 1.20V 基准电压用作一个可调器件。提供的封装型式包括 5 引脚 TO-220、5 引脚 DD-PAK 以及耐热增强型 8 引脚 MSOP 和扁平 (0.75mm) 8 引脚 3mm x 3mm DFN 封装。
