A capacitor connected from this pin to GND sets the delay time for start-up sequence and sets the fault
timeout time
Open drain output for gate drive of optional V
Drain of the internal N channel boost FET; for EL7586, pin 4 is not connected
Positive LDO base drive; open drain of an internal N channel FET
Positive LDO voltage feedback input pin; regulates to 1.2V nominal
Logic LDO base drive; open drain of an internal N channel FET
Logic LDO voltage feedback input pin; regulates to 1.2V nominal
Low noise signal ground
Negative LDO base drive; open drain of an internal P channel FET
