7.3.10 Power-Up Characteristics

The DCP02 series of devices do not include a soft-start feature. Therefore, a high in-rush current during power up is expected. To ensure a more stable start-up, allow the input voltage to be in regulation before enabling the device. Refer to the Section 7.4.1 section on how to disable/enable the device. Figure 7-6 shows the typical start-up waveform for a DCP020505P when enabled after the input voltage is in regulation. Figure 7-3 shows the typical start-up waveform for a DCP020505P, operating from a 5-V input with no load on the output. Figure 7-4 shows the start-up waveform for a DCP020505P starting up into a 10% load. Figure 7-5 shows the start-up waveform into a full (100%) load.
