GENERAL DESCRIPTION
The CM431L is a low voltage three terminal adjustable shunt
regulator with thermal stability guaranteed over temperature.
The output voltage can be adjusted to any value from 1.24V
(V
REF
)to
20V with two external resistors. The CM431L has a
typical dynamic output impedance of 0.25Ω. Active output
circuitry provides a very sharp turn on characteristic, making
the CM431L an excellent replacement for zener diodes.
The CM431L shunt regulator is available in four voltage
tolerances(0.5%, 0.7%, 1.0% and 2.0%)and four package
options (SOT-23-3, SOT-23-5, SOT-89, TO-92, and SOP-8).
Four voltage tolerances allow the designer the opportunity to
select the proper cost/tolerance for their application.

动图详解电压电流的超前与滞后
电压电流的超前与滞后这个概念是相对于电流和电压之间的关系而说的。也就是说,比如是容性负载(电容器),那么他会导致最终电流超前90度,如果是电感则产生最终电流超前-90度(即滞后90度)反过来说,在平面直角坐标系中,假设电压为X轴水平方向,则是否超前则为Y轴垂直方向,当为容性负载时为Y正半轴部分,感性负载为Y负半轴部分无论是正超前还是负超前(滞后)都会导致功率因数下降,而纯阻性负载其超前角是0度,这个时候功率因数为1正因为容性和感性具有这种相反的性质,那么当使用电动机等感性负载时,会导致严重...

模电及电源技术难得入门好书推荐给大家
1.《晶体管电路设计》上下[日]铃木雅臣科学出版社出版 推荐原因:这本书讲的通俗易懂,实践偏于理论,这样容易激发初学者的兴趣。中专,高中毕业的人都能看懂。 《电子电路基础——高性能模拟电路和电流模技术》编著:张凤言高等教育出版社出版 推荐原因:当你有点入门后,看这本书提高很好,因为这本书的大部分内容是取材美国《模拟集成电路设计》GARY的章节,语言浅显但又不失深度,让你很容易将基础提高,这本书要反复的看,多看几遍,这是我提倡,任何书籍都要多看几遍,在不同的时间段,不同的年龄段,面对...
