您好!
我想选一颗LDO,输入电压是5V,输出是3.9V,实际最大负载电流为1A,我认为选用1.5A的LDO应该就可以了。请帮忙推荐一颗呢。谢谢~~

Hi
符合的芯片很多,见TI芯片list: http://www.ti.com.cn/lsds/ti_zh/power-management/single-channel-ldo-products.page?&virtualTreeURL=D_ATTRIBUTE_3001166|EQ|Yes&filter=a1166|EQ|Yes#p451max=1.2;7.5 (设置输出电流大于1.2A即可)
可以选择TPS7A92, TPS74001DPT 等等(注意选择热阻尽量小的芯片)
