For low current rails, a linear regulator with a user-programmable soft-start minimizes stress on the input power source by reducing the capacitive inrush current on start-up, especially from highly capacitive loads or with processors requiring many bypass capacitors. The TPS74801 adjustable linear regulator provides a monotonic (non-negative slope) soft-start that is well-suited for powering many different types of processors. Figure 5-1 illustrates the start-up waveform showing the start-up times varying over several soft start capacitor values.
