目录7.相关产品 产品概述 返回TOP CXLD64191系列产品是实现了高精度,高纹波抑制,低压差的200mA高速LDO电压调整器IC。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,防止冲击电流电路等构成。采用激光微调技术能在内部以0.05V的间隔±1.0%以内的精度,在1.2V~3.6V的范围内设定输出电压。控制CE引脚能停止电压调整器的输出使其成待机状态。此外,在待机状态下,能通过VOUT引脚与VSS引脚之间的内部开关使输出滤波电容(CL)中的充电电荷放电。能使VOUT引脚高速地返回低水平。用于稳定输出的电容(CL)还能对应陶瓷电容等低ESR电容。由于具有良好的瞬态响应特性,即使在负载变动时,也能提供稳定的输出电压。内置了过电流保护电路,当输出电流达到限定电流时保护电路开始工作。The CXLD64191 series is a 200mA high speed LDO regulator that features high accurate high ripple rejection and low dropout. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit and an inrush current prevention circuit. The output voltage is selectable in 0.05V increments (Accuracy ±1%) within the range of 1.2V to 3.6V. The CE function enables the circuit to be in stand-by mode as well as the electric charge at the output capacitor CL to be discharged via the internal switch, and the VOUT pin quickly returns to the Low level. The series is also compatible with low ESR ceramic capacitors, which provides stable output voltage. This stability can be maintained even during load fluctuations due to the excellent transient response. The over current prevention circuit will operate when the output current reaches the current limit. 产品特点 返回TOP
