目录7.相关产品 产品概述 返回TOP CXLD64204系列产品是实现了高精度,高纹波抑制,低消耗电流,附带ON/OFF功能的负电压调整器。本IC由基准电源,误差放大器,驱动晶体管,限定电流电路,相位补偿电路,过热保护电路等构成。用正电压控制CE引脚时便可使用,通过输入低(L)电平,整个IC成为电路OFF的待机状态。此外,在待机状态时,用VOUT引脚与GND之间的内部开关能使输出电容(CL)的充电电荷放电。此功能可使输出引脚高速地返回接地电平。内置了反馈型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150oC时,保护电路开始工作。The CXLD64204 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifier, driver transistor, current limiter and phase compensator. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the electric charge at the output capacitor (CL) will be discharged via the internal auto-discharge switch and as a result the -VOUT pin quickly returns to the VSS level. The over current protection circuit will operate when the output current reaches limit current. The thermal shutdown circuit will operate when the junction temperature reaches limit temperature. 产品特点 返回TOP
