CXLD64198系列是内置N沟道FET,可输出400mA的高速LDO电压调整器。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。CXLD64198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，电压调整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

The series is ideally suited to the applications which require very low dropout voltage operation and consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a fold back circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit, soft-start circuit and a phase compensation circuit. Output voltage is selectable in 0.05V increments within a range of 0.7V to 1.8V using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (CL). The over current protection circuit (the current limiter and the fold back circuit) as well as the thermal shutdown circuit (the TSD circuit) are built-in. These two protection circuits will operate when either the output current reaches the current limit level or the junction temperature reaches the temperature limit level. With the built-in UVLO function, the regulator output is forced OFF when the voltage level at the VBIAS pin or the VIN pin falls below the UVLO voltage level. With the soft-start function, the inrush current from VIN to VOUT for charging CL at start-up can be reduced and makes the VIN stable. The CE function enables the output to be turned off and the series to be put in stand-by mode resulting in greatly reduced power consumption. At the time of entering the stand-by mode, the series enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge switch which is located between the VOUT pin and the VSS pin. As a result the VOUT pin quickly returns to the VSS level.
