After being enabled, the device starts operating. The average current limit ramps up from an initial 400 mA following the output voltage increasing. At an output voltage of about 1.2 V, the current limit is at its nominal value. If the output voltage does not increase, the current limit does not increase. The device implements no timer. Thus, the output voltage overshoot at startup, as well as the inrush current, remains at a minimum. The device ramps up the output voltage in a controlled manner even if a large capacitor is connected at the output.
