LDO功率损耗:https://training.eeworld.com.cn/course/4375
To get the most out of your LDO application, the LDO power dissipation needs to be carefully considered. The power dissipation in the LDO is determined by the voltage drop across the LDO multiplied by the current passing through the LDO. Increasing the LDO voltage drop or the LDO current quickly leads to higher dissipation. But how much power can you dissipate in the LDO? Learn more about package power dissipation and how to improve your thermal design in our tutorial video.
