10. Delay between LDO2 and LDO1 disabled.
VEXT goes active low.
VEXT 32 msec de-bounce period.
Delay between LDO1 and LDO2 enables.
Both LDO1 and LDO2 outputs reach 95% of respective output voltage, start Reset timer.
Reset delay.
Period between Reset and PS_HOLD going high is not relevant since VEXT is low
PS_HOLD goes low but LDOs continue to run since VEXT is low.
PS_HOLD is low and VEXT goes high, RST pin goes low.
Delay between RST going low and LDO2 disabled.
