目录7.相关产品 产品概述 返回TOP CXLD64184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。本IC由基准电压源,误差放大器,驱动晶体管,电流限制电路,相位补偿电流,过热保护电流,突入电流防止电路等构成。给CE端子输入低电平能使IC成待机状态。在待机状态下,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。稳定输出用的电容(CL)可使用陶瓷电容等低ESR的电容。输出电压通过激光微调在1.2V~4.0V的范围内能以0.05V的间隔设定。内置了过电流保护电路和过热保护电路,当输出电流达到限制电流或结温度达到限制温度时,保护电路将开始工作。The CXLD64184 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption. The series 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
