... Staged turn-on and soft-start minimize start-up input current surges without causing excessive device turn-on time. Power Control The ISL9000A has two separate enable pins, EN1 and EN2, to individually control power to each of the LDO outputs. When both EN1 and EN2 are low, the device is in shutdown 9 ...

... ISL9000A delays the VO2 turn-on until the VO1 output reaches its target level. If EN2 is brought high, and EN1 goes high before VO2 starts its output ramp, then VO1 turns on first and, the ISL9000A delays the VO2 turn-on until the VO1 output reaches its target level. ...
