• 描述 The LT™1529/LT1529-3.3/LT1529-5 are 3A low dropout regulators with micropower quiescent current and shutdown. LT™1529/LT1529-3.3/LT1529-5是3A低压降稳压器与微静态电流和关机。 The devices are capable of supplying 3A of output current with a dropout voltage of 0.6V.这些器件能够提供3A输出电流与0.6V的压降。 Designed for use in battery-powered systems, the low quiescent current, 50µA operating and 16µA in shutdown, make them an ideal choice.在使用电池供电系统设计，低静态电流50μA运行和关机16μA，使他们的理想选择。 The quiescent current is well controlled; it does not rise in dropout as it does with many other low dropout PNP regulators.静态电流得到很好的控制，它不辍学上升，因为它与其他许多低压差PNP稳压器。 Other features of the LT1529 /LT1529-3.3/LT1529-5 include the ability to operate with small output capacitors.的LT1529 / LT1529-3.3/LT1529-5的其他功能还包括小型输出电容器的操作能力。 They are stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability.他们是与仅3.3μF的输出稳定10μF和100μF之间，而最旧设备需要稳定。 Small ceramic capacitors can be used, enhancing manufacturabiltiy.可以使用小型的陶瓷电容器，，加强manufacturabiltiy。 Also the input may be connected to voltages lower than the output voltage, including negative voltages, without reverse current flow from output to input.也可输入电压低于输出电压，包括负电压，无反向电流从输出到输入连接。 This makes the LT1529/LT1529-3.3/LT1529-5 ideal for backup power situations where the output is held high and the input is at ground or reversed.这使得LT1529/LT1529-3.3/LT1529-5理想的备用电源情况下，高举输出和输入的是在地面或逆转。 Under these conditions, only 16µA will flow from the OUTPUT pin to ground.在这些条件下，只有16μA输出引脚将流入到地面。 The devices are available in 5-lead TO-220 and 5-lead DD packages.该器件提供5引脚TO-220和5引线DD包。
