目录7.相关产品 产品概述 返回TOP CXLD64183系列产品是实现了高精度,低噪声,高纹波除去率,低压差,低消耗电流的高速LDO电压调整器。内部由基准电压源,误差放大器,驱动晶体管,电流限制电路,过热保护电路,相位补偿电路等构成。给CE端子输入低电平能使IC成待机状态。待机状态时,由VOUT端子-VSS端子之间的内部开关能使稳定输出用电容(CL)的充电电荷放电。此放电功能可使VOUT端子高速地返回VSS电位。内置了过电流保护电路和过热保护电路,当输出电流达到限定电流或结温度达到限定温度时,保护电路将开始工作。The CXLD64183 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal protection circuit, and a phase compensation circuit. The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this stand-by mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as a result the VOUT pin will quickly return to the VSS level. Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output current reaches the current limit level or junction temperature reaches the temperature limit. 产品特点 返回TOP
