7.3.5 Specified Start-Up Performance

The OPA2333P has a dedicated start-up circuit that ensures a fast, repeatable startup for all supply conditions. The OPA2333P is specified to have a maximum start-up time that is production-tested as illustrated in the configuration shown in Figure 21. Start-up time is defined as the time from when the power supply reaches the minimum specified voltage to the time the output has settled to within 20 mV of the nominal value. See Figure 22.
