The Device has integrated over-current protection, over-temperature protection and UVLO (Under Voltage Lockout) to provide for a fail safe solution with no external components.

这个器件集成了过流保护、过温保护和U掉压关断的功能，可以不需外转器件实现保护解决方案。

Further, in most of these cases small ceramic capacitors can be used and there no further need for external components.

此外，在多数情况下，可以使用小型陶瓷电容器且不再需要外部组件。
