... The under voltage lockout inhibits the outputs and the changing of the soft−start capacitor when V nominal. The output stages are totem−pole design capable of sinking and sourcing in excess of 200 mA. The output stage of the SG3525A features NOR logic resulting in a low output for an off−state. Features 8 Operation 5.1 V " ...
