AMS1117是什么工作原理?AMS1117与LM1117的区别是什么?什么是线性调整率和负载调整率?

LM1117输入电压12V,输出3.3V,温度在50度左右,正常吗?LM正常工作是温度多少?

用LM1117作为3.3V和5.0V的电源输出,但是发热很厉害,手放上烫的很厉害,请问这是什么问题?而买的开发板上也用的1117但是不会出现发热严重的问题。

LM1117 5V有没有直插的封装?说明书里的TO252和SOT223都是贴片?

此电路出现一个奇葩问题:接上稳压芯片LM1117(3.3)输出接近5V,大概4.8左右,去掉芯片反而输出对了3.1V大约,输入是5V(5.4V左右),奇怪,特请各位大神看看问题,不胜感激...

你好,我在使用ad9914评估板,P300引脚是3.3v和1.8v电源供电,想问普通的LM1117稳压芯片做电源电路可以么,还是使用LDO稳压器芯片做电源电路?

我在使用DIX9211时,按照datasheet上的电路设计线路板,第一次设计的PCB为12V直流经淘宝上买的LM1117-3.3(贴片)降压为3.3V供电。板子焊好后试机,一上电

求大神解决,我用LM317典型电路得到的5V电压作为AMS1117-3.3的输入,可是在连接后测得的317得输出变成了2.45V,固定输出3.3V变成1.44V,断开后重新测试,317输出还是为5V,而1117的电路
