= 1.5 V.
2. All transient values are guaranteed by design, not production tested.
3. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. This
specification does not apply for output voltages below 1.5 V.
4. Turn-on time is time measured between the enable input just exceeding V
EN
high value and the output voltage just
reaching 95 % of its nominal value.

LD39030SJ Soft-start function

6 Soft-start function
The LD39030S has an internal soft-start circuit. By increasing the startup time up to 100 μs,
without the need of any external soft-start capacitor, this feature is able to reduce the
regulator inrush current to 1/3 of the original value.
