PRODUCTION DATA.
This function forces VOUT to increase at a controlled rate during start-up. During soft start, the error amplifier’s reference voltage ramps from 0 V to its nominal value of 0.6 V in approximately 600 µs. This forces the regulator output to ramp up in a controlled fashion, which helps reduce inrush current.
