LT1764A 3A、快速瞬态响应、低噪声 、LDO 稳压器
LT®1764A 是一款低压差稳压器，专为实现快速瞬态响应而优化的。该器件能提供 3A 的输出电流和一个 340mV 的压差电压。工作静态电流为 1mA，并在停机模式中减小至 <1μA。静态电流处于良好受控状态；与其他许多稳压器不同，此器件的静态电流在压差情况下不会增大。除了快速瞬态响应之外，LT1764A 还拥有非常低的输出电压噪声，从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。LT1764A 稳压器可在采用低至 10μF 的输出电容器时保持稳定。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。LT1764A 稳压器采用 5引脚 TO-220 和 DD 封装以及 16 引脚 FE 封装。
