1.0V低输入电压400mA LDO电压稳压器

XC6601系列是内置N沟道FET,可输出400mA的高速LDO电压稳压器。即使是低输出电压也可通过超低导通阻抗高效地输出电流。该系列适用于低输入电压以及要求低输入输出电压差的应用。

XC6601系列内部由基准电压源,误差放大器,驱动三级管,定电流限制电路,FOLD-BACK电路,过热保护电路（TSD）,欠压锁闭电路（UVLO）和相位补偿电路组成。

通过激光微调技术，输出电压范围是0.7V～1.8V，0.05V间隔设定。输出电容（CL）可使用低ESR类型的电容。

当输出电流达到限制电流或者结温度达到限制温度的时候，过流保护电路（定电流限制电路,FOLD-BACK电路）和过热保护电路（TSD）就会工作，起到保护IC的作用。当VBIAS和VIN端子之间的电压比UVLO电压低的时候，电压稳压器的输出就会被关断。

在CE端子输入低电平的时候，IC进入待机模式，消耗电流会大幅减小。同时，进入待机模式的时候，输出电容（CL）上的电荷可通过VOUT端子和VSS端子之间的内部开关释放，使电压快速返回到VSS电平。
