7.3.3 Soft Startup

The device has an internal soft start circuit which ramps up the output voltage to the nominal voltage during a soft start time of typically 0.8ms. This avoids excessive inrush current and creates a smooth output voltage slope. It also prevents excessive voltage drops of primary cells and rechargeable batteries with high internal impedance. The device is able to monotonically start into a pre-biased output capacitor. The device starts with the applied bias voltage and ramps the output voltage to its nominal value.
