VDROP

Dropout Voltage

1. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100mV below its nominal

value (does not apply to input voltages below 2.0V).

Turn On Time

2. Turn on time is time measured between the enable input just exceeding the VEN high value and the output volt-

age just reaching 95% of its nominal value.
