3

Dropout voltage is defined as the input to output voltage differential when the input voltage is set to the nominal output voltage. Dropout applies only for output

voltages below −2 V.

4

Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% 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 threshold for a

−3.0 V output voltage is defined as the current that causes the output voltage to drop to 90% of −3.0 V, or −2.7 V.
