REG104FA5.0引脚接法以及最大输出电流

Other Parts Discussed in Thread: REG104

因为REG104的型号很多,我们买的REG104FA5.0芯片后缀是712Z10V,请问后缀里面的10V是最大输入电压吗?芯片datasheet上面写的是最大输入电压15V,输出电流为1A。为什么不一样啊?芯片封装为TO-263,请问这个芯片的正确接法是什么啊?我们按datasheet上面接的不对,把1,2,4脚短接,才能输出5V,。输出的5V电压只能给一个芯片供电,这是正确。给两个芯片一起供的时候就出错了。5V电压直接变成了0.67V左右。请问这是什么情况啊?
