有电源工作状态信号输出:不少便携式电子产品中有单片机，在电源因过热或电池低电压而使输出电压下降一定百分数时，电源IC有一个电源工作状态信号输给单片机，使单片机复位。利用这个信号也可以做成电源工作状态指示（当电池低电压时，有LED显示)。

耗电小及关闭电源功能:新型电源IC的静态电流都较小，一般为几十uA到几百uA。个别微功耗的线性稳压器其静态电流仅1.1uA。

另外，不少电源IC有关闭电源控制端功能（用电平来控制)，在关闭电源状态时IC自身耗电在1uA左右。由于它可使一部分电路不工作，可大大节省电能。例如，在无线通信设备上，在发送状态时可关闭接收电路;在未接收到信号时可关闭显示电路等。

Power working status signal output: many portable electronic products have a single chip microcomputer, in the power supply due to overheating or battery low voltage and the output voltage drops by a certain percentage, the power IC has a power supply working status signal to the single chip microcomputer, so that the single chip microcomputer reset. This signal can also be used to indicate the working status of the power supply (when the battery is low voltage, there is an LED display).

Small power consumption and power off function: The static current of the new power supply IC is small, generally tens of uA to hundreds of uA. The static current of individual low-power linear regulators is only 1.1uA.

In addition, many power ics have the function of turning off the power control terminal (controlled by the level), and the IC itself consumes about 1uA when the power is turned off. Because it can make a part of the circuit does not work, can greatly save energy. For example, on wireless communication devices, the receiving circuit can be turned off during the sending state; The display circuit can be turned off when the signal is not received.
