LT1963A 1.5A、低噪声、快速瞬态响应 LDO 稳压器
LT®1963A 系列是低压差稳压器，专为实现快速瞬态响应而优化。这些器件可提供 1.5A 的输出电流和一个 340mV 的压差电压。工作静态电流为 1mA，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不同，它在压降条件下并不上升。除了快速瞬态响应之外，LT1963A 稳压器还具有非常低的输出噪声，因而使其非常适合于敏感的 RF 电源应用。
输出电压范围为 1.21V 至 20V。LT1963A 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、电流限制、热限制和反向电流保护。该器件可提供 1.5V、1.8V、2.5V、3.3V 的固定输出电压，并可用作一款具 1.21V 基准电压的可调型器件。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。
