2. Recommended Operating Conditions
<Notes on turning the power on>
The maximum power rising slope ( V/ t) must be 0.05 V/ s when the 3 V power supply is turned on.
It takes about 100 s until the 2.5 V power supply becomes stable after the 3 V power supply becomes stable.
Keep INIT input during that interval.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
