LT1963A系列为低压差稳压器，针对快速瞬态响应进行了优化。这些器件能够提供1.5A输出电流，具有340mV压差。工作静态电流为1mA，关断时降至<1μA。静态电流处于良好受控状态；如许多其他稳压器不同，在压差模式下不会上升。除了快速瞬态响应之外，LT1963A稳压器具有极低的输出噪声，使其非常适合敏感型RF电源应用。
输出电压范围为1.21V至20V。LT1963A稳压器能够使用低至10μF的输出电容稳定工作。内部保护电路包括电池反接保护、限流、限热以及反向电流保护功能。这些器件提供1.5V、1.8V、2.5V、3.3V的固定输出电压，并可用作具有1.21V基准电压的可调器件。LT1963A稳压器采用5引脚TO-220、DD、3 引脚SOT-223、8引脚SO和16引脚TSSOP封装。
