Power Management Products
The AP1161 is an LDO regulator IC with On / Off control that can stably supply output current of 300mA.
The AP1161 has built-in voltage monitoring function of the regulator output, and it is possible to detect overvoltage and low voltage. With the voltage monitoring function self-diagnosis function, it is possible to detect its own trouble. In addition, overcurrent protection and overheat protection circuit are built in as protection function.
