Notes:
5) Parameter is guaranteed by design, not production tested.
6) Resistors for V
OUT
measurement are 10k, 14k, 1%
7) The ground current does not include current through feedback current
8) Dropout Voltage is defined as the input to output differential when the output voltage drops 1% below its nominal value
9) VFEEDBACK is 90% of the regulated value with 10k pull-up to 5V
