7.3.2 Soft Start

When an input voltage is applied to the TPS2116 and the output voltage is lower than 1 V, the output will be brought up with soft start to minimize the inrush current due to output capacitance. However, when the device switches from one power supply to another (switchover) and VOUT > 1 V, soft start is not used to minimize the output voltage drop. For linear soft start behavior, it is recommended to have an output capacitance of at least 0.1 µF.
