MAX8556ETE+T产品描述
4A、超低输入电压LDO稳压器
MAX8556/MAX8557低压差线性稳压器的输入电压可低至1.425V,能够连续输出4A电流而压差仅为100mV。输出电压可以在0.5V至VIN - 0.2V的范围内调节。
采用内部p沟道MOSFET导通晶体管,无论负载电流和压差如何,MAX8556/MAX8557可以维持800µA的低典型电源电流。使用p沟道MOSFET无需附加的外部电源或引起噪声的内部电荷泵。器件的其它特点还包括逻辑控制的关断模式、内置软启动、带有折返式限流的短路保护和热过载保护。MAX8556拥有POK输出,当调节器的输出在其额定输出电压的±10%范围内时POK输出变高。MAX8557提供上电复位输出,当输出达到额定输出电压的90%并持续140ms后,上电复位输出变高。
MAX8556/MAX8557采用带裸露焊盘的16引脚薄型QFN 5mm x 5mm封装。
