1 _{Accuracy when OUT is connected directly to ADJ. When OUT voltage is set by external feedback resistors, absolute accuracy in adjust mode depends on the tolerances}
of resistors used.
2 _{Based on an end-point calculation using 1 mA and 50 mA loads. See Figure 6 for typical load regulation performance for loads less than 1 mA.}
3 _{Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output}
voltages above 4 V.
4 _{Start-up time is defined as the time between the rising edge of EN to OUT being at 95% of its nominal value.}
5 _{Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 5.0 V}
output voltage is defined as the current that causes the output voltage to drop to 90% of 5.0 V, or 4.5 V.
