目录7.相关产品 产品概述 返回TOP CXLD64188系列产品是实现了高精度,低噪声,高纹波抑制,低压差,低消耗电流的高速LDO电压调整器。由于300mA的高速LDO电压调整器IC采用了最大尺寸仅为0.75mm×0.75mm, h=0.3mm 的超小型封装“LGA-4B01”,能实现高密度的设计。本IC由基准电压源,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。防止冲击电流电路等构成。从CE引脚输入低电平能使IC成待机状态,用VOUT引脚与VSS引脚之间的内部开关能使输出电容(CL)的充电电荷放电。使得VOUT引脚高速地返回VSS电平。用于输出滤波电容(CL)还能对应陶瓷电容等低ESR电容。激光微调技术能在内部以0.05V的间隔,在1.2V~4.0V的范围设定输出电压。内置了过电流保护电路和过热保护电路。当输出电流达到了限定电流或结温度达到了限定温度时,保护电路开始工作。The CXLD64188 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption. Housed in the ultra-small LGA-4B01 (0.75 x 0.75, h=0.3mm MAX.) package, the CXLD64188 is ideal for space-saving design. The CXLD64188 consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit, a thermal shutdown circuit and an inrush current protection circuit. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin quickly returns to the VSS level. The output stabilization capacitor CL is also compatible with low ESR ceramic capacitors. The output voltage is selectable in 0.05V increments within the range of 1.2V to 4.0V which fixed by laser trimming technologies. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level. 产品特点 返回TOP
