LSF0108的1.8V使用的是TLV70218,3.3V使用的是1117-3.3 原理如下图所示 测试1.8V这端始终是

AMS1117和SGM2019这两种稳压芯片,各位觉得那种比较好?AMS1117输出电流据说是1A,SGM2019在文档上没写,如果我需要接FPGA的EP4CE6E22C8N芯片,里面有1.2v,3.3

AMS1117的输出可以为12V吗?看网上资料都是3.3比较多

AMS1117手册上说 压差最大为1.3V,5V至3.3V电路压差为1.7V,超过了说明书上1.3

`ARM2440 外接 5v 电源,需要 3.3V、2.5V、1.8V 如何产生?有原理图吗?`

转换时是双向的,每个方向都是input/output但是在用于2.5v转1.8V时,是单向的,2.5V是input,output是1.8V那侧。@这样的话,

AMS1117-3.3为什么输出电压仅有0.9V,并且5V输入电压也变成了4.3V?仅有电源模块时AMS1117芯片上3

使用Knitex 7,主SPI串行模式。串行闪存数据条:MOSI,DIN,在UG470中列为双向。对于串行闪存,我需要将这些(和其他)IO电压从2.5V转换为1.8V。我可以使用单向电压转换器(显然

想用SPX5205替换AMS1117稳出3.3V给32芯片供电,AMS1117时间稍长就会发热,不知道SPX5205效果会不会好点。
