The JW® 7805 is a low noise low-dropout (LDO)  voltage regulator with enable function that  operates from 1.8V to 5.5V. It provides up to  300mA of output current and offers low-power  operation in miniaturized packaging. JW7805  supports fixed output voltage 0.9V, 1.0V, 1. ...
技术资料 LDO环路分析及补偿
低压差线性稳压器(Low Dropout Voltage Regulator,LDO)属于线性稳压器的一种,但由于其压差较低,相对于一般线性稳压器而言具有较高的转换效率。但在电路稳定性上有所下降,而且LDO有着较高的输出电阻,使得输出极点的位置会随着负载情况有很大关系。因此需要对LDO进行频率补偿来满足其环路稳定性要求。内容安排上第一节 ...
技术资料 基于ldo白光led驱动集成电路设计论文
白光LED(White Light-Fmitting Diode)以其高效、节能、环保、寿命长、无污染等优点逐渐取代传统的白炽灯成为新一代照明光源。与此同时,与LED配套的驱动集成电路的研发也由LED的应用逐渐普及而得到长足的发展。本文对基于LDO(Low dropout voltage 1inear regulator)恒流型的白光LED驱动集成电路进行了设计分析。该驱动 ...
