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