1. All transient values are guaranteed by design, not production tested
2. 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
3. PG pin floating
4. Turn-on time is time measured between the enable input just exceeding VEN high value and the output voltage just
reaching 95% of its nominal value
